text: To understand the function of neuronal circuits, it is crucial to disentangle
the connectivity patterns within the network. However, most tools currently used
to explore connectivity have low throughput, low selectivity, or limited accessibility.
Here, we report the development of an improved packaging system for the production
of the highly neurotropic RVdGenvA-CVS-N2c rabies viral vectors, yielding titers
orders of magnitude higher with no background contamination, at a fraction of
the production time, while preserving the efficiency of transsynaptic labeling.
Along with the production pipeline, we developed suites of ‘starter’ AAV and bicistronic
RVdG-CVS-N2c vectors, enabling retrograde labeling from a wide range of neuronal
populations, tailored for diverse experimental requirements. We demonstrate the
power and flexibility of the new system by uncovering hidden local and distal
inhibitory connections in the mouse hippocampal formation and by imaging the functional
properties of a cortical microcircuit across weeks. Our novel production pipeline
provides a convenient approach to generate new rabies vectors, while our toolkit
flexibly and efficiently expands the current capacity to label, manipulate and
image the neuronal activity of interconnected neuronal circuits in vitro and in
vivo.

text: "AMPA-type glutamate receptors (AMPARs) mediate rapid signal transmission
at excitatory\r\nsynapses in the brain. Glutamate binding to the receptor’s ligand-binding
domains (LBDs)\r\nleads to ion channel activation and desensitization. Gating
kinetics shape synaptic transmission\r\nand are strongly modulated by transmembrane
AMPAR regulatory proteins (TARPs)\r\nthrough currently incompletely resolved mechanisms.
Here, electron cryo-microscopy\r\nstructures of the GluA1/2 TARP-γ8 complex, in
both open and desensitized states\r\n(at 3.5 Å), reveal state-selective engagement
of the LBDs by the large TARP-γ8 loop (‘β1’),\r\nelucidating how this TARP stabilizes
specific gating states. We further show how TARPs alter\r\nchannel rectification,
by interacting with the pore helix of the selectivity filter. Lastly, we\r\nreveal
that the Q/R-editing site couples the channel constriction at the filter entrance
to the\r\ngate, and forms the major cation binding site in the conduction path.
Our results provide a\r\nmechanistic framework of how TARPs modulate AMPAR gating
and conductance."

text: "One of the fundamental questions in Neuroscience is how the structure of
synapses and their physiological properties are related. While synaptic transmission
remains a dynamic process, electron microscopy provides images with comparably
low temporal resolution (Studer et al., 2014). The current work overcomes this
challenge and describes an improved “Flash and Freeze” technique (Watanabe et
al., 2013a; Watanabe et al., 2013b) to study synaptic transmission at the hippocampal
mossy fiber-CA3 pyramidal neuron synapses, using mouse acute brain slices and
organotypic slices culture. The improved method allowed for selective stimulation
of presynaptic mossy fiber boutons and the observation of synaptic vesicle pool
dynamics at the active zones. Our results uncovered several intriguing morphological
features of mossy fiber boutons. First, the docked vesicle pool was largely depleted
(more than 70%) after stimulation, implying that the docked synaptic vesicles
pool and readily releasable pool are vastly overlapping in mossy fiber boutons.
Second, the synaptic vesicles are skewed towards larger diameters, displaying
a wide range of sizes. An increase in the mean diameter of synaptic vesicles,
after single and repetitive stimulation, suggests that smaller vesicles have a
higher release probability. Third, we observed putative endocytotic structures
after moderate light stimulation, matching the timing of previously described
ultrafast endocytosis (Watanabe et al., 2013a; Delvendahl et al., 2016). \r\n\tIn
addition, synaptic transmission depends on a sophisticated system of protein machinery
and calcium channels (Südhof, 2013b), which amplifies the challenge in studying
synaptic communication as these interactions can be potentially modified during
synaptic plasticity. And although recent study elucidated the potential correlation
between physiological and morphological properties of synapses during synaptic
plasticity (Vandael et al., 2020), the molecular underpinning of it remains unknown.
Thus, the presented work tries to overcome this challenge and aims to pinpoint
changes in the molecular architecture at hippocampal mossy fiber bouton synapses
during short- and long-term potentiation (STP and LTP), we combined chemical potentiation,
with the application of a cyclic adenosine monophosphate agonist (i.e. forskolin)
and freeze-fracture replica immunolabelling. This method allowed the localization
of membrane-bound proteins with nanometer precision within the active zone, in
particular, P/Q-type calcium channels and synaptic vesicle priming proteins Munc13-1/2.
First, we found that the number of clusters of Munc13-1 in the mossy fiber bouton
active zone increased significantly during STP, but decreased to lower than the
control value during LTP. Secondly, although the distance between the calcium
channels and Munc13-1s did not change after induction of STP, it shortened during
the LTP phase. Additionally, forskolin did not affect Munc13-2 distribution during
STP and LTP. These results indicate the existence of two distinct mechanisms that
govern STP and LTP at mossy fiber bouton synapses: an increase in the readily
realizable pool in the case of STP and a potential increase in release probability
during LTP. “Flash and freeze” and functional electron microscopy, are versatile
methods that can be successfully applied to intact brain circuits to study synaptic
transmission even at the molecular level.\r\n"

text: Complex wiring between neurons underlies the information-processing network
enabling all brain functions, including cognition and memory. For understanding
how the network is structured, processes information, and changes over time, comprehensive
visualization of the architecture of living brain tissue with its cellular and
molecular components would open up major opportunities. However, electron microscopy
(EM) provides nanometre-scale resolution required for full in-silico
reconstruction1–5, yet is limited to fixed specimens and
static representations. Light microscopy allows live observation, with super-resolution
approaches6–12 facilitating nanoscale visualization, but
comprehensive 3D-reconstruction of living brain tissue has been hindered by tissue
photo-burden, photobleaching, insufficient 3D-resolution, and inadequate signal-to-noise
ratio (SNR). Here we demonstrate saturated reconstruction of living brain tissue.
We developed an integrated imaging and analysis technology, adapting stimulated
emission depletion (STED) microscopy6,13 in extracellularly
labelled tissue14 for high SNR and near-isotropic resolution.
Centrally, a two-stage deep-learning approach leveraged previously obtained information
on sample structure to drastically reduce photo-burden and enable automated volumetric
reconstruction down to single synapse level. Live reconstruction provides unbiased
analysis of tissue architecture across time in relation to functional activity
and targeted activation, and contextual understanding of molecular labelling.
This adoptable technology will facilitate novel insights into the dynamic functional
architecture of living brain tissue.

text: Mapping the complex and dense arrangement of cells and their connectivity
in brain tissue demands nanoscale spatial resolution imaging. Super-resolution
optical microscopy excels at visualizing specific molecules and individual cells
but fails to provide tissue context. Here we developed Comprehensive Analysis
of Tissues across Scales (CATS), a technology to densely map brain tissue architecture
from millimeter regional to nanoscopic synaptic scales in diverse chemically fixed
brain preparations, including rodent and human. CATS leverages fixation-compatible
extracellular labeling and advanced optical readout, in particular stimulated-emission
depletion and expansion microscopy, to comprehensively delineate cellular structures.
It enables 3D-reconstructing single synapses and mapping synaptic connectivity
by identification and tailored analysis of putative synaptic cleft regions. Applying
CATS to the hippocampal mossy fiber circuitry, we demonstrate its power to reveal
the system’s molecularly informed ultrastructure across spatial scales and assess
local connectivity by reconstructing and quantifying the synaptic input and output
structure of identified neurons.

text: Synapses of glutamatergic mossy fibers (MFs) onto cerebellar unipolar brush
cells (UBCs) generate slow excitatory (ON) or inhibitory (OFF) postsynaptic responses
dependent on the complement of glutamate receptors expressed on the UBC’s large
dendritic brush. Using mouse brain slice recording and computational modeling
of synaptic transmission, we found that substantial glutamate is maintained in
the UBC synaptic cleft, sufficient to modify spontaneous firing in OFF UBCs and
tonically desensitize AMPARs of ON UBCs. The source of this ambient glutamate
was spontaneous, spike-independent exocytosis from the MF terminal, and its level
was dependent on activity of glutamate transporters EAAT1–2. Increasing levels
of ambient glutamate shifted the polarity of evoked synaptic responses in ON UBCs
and altered the phase of responses to in vivo-like synaptic activity. Unlike classical
fast synapses, receptors at the UBC synapse are virtually always exposed to a
significant level of glutamate, which varies in a graded manner during transmission.

text: "Background: To understand information coding in single neurons, it is necessary
to analyze subthreshold synaptic events, action potentials (APs), and their interrelation
in different behavioral states. However, detecting excitatory postsynaptic potentials
(EPSPs) or currents (EPSCs) in behaving animals remains challenging, because of
unfavorable signal-to-noise ratio, high frequency, fluctuating amplitude, and
variable time course of synaptic events.\r\nNew method: We developed a method
for synaptic event detection, termed MOD (Machine-learning Optimal-filtering Detection-procedure),
which combines concepts of supervised machine learning and optimal Wiener filtering.
Experts were asked to manually score short epochs of data. The algorithm was trained
to obtain the optimal filter coefficients of a Wiener filter and the optimal detection
threshold. Scored and unscored data were then processed with the optimal filter,
and events were detected as peaks above threshold.\r\nResults: We challenged MOD
with EPSP traces in vivo in mice during spatial navigation and EPSC traces in
vitro in slices under conditions of enhanced transmitter release. The area under
the curve (AUC) of the receiver operating characteristics (ROC) curve was, on
average, 0.894 for in vivo and 0.969 for in vitro data sets, indicating high detection
accuracy and efficiency.\r\nComparison with existing methods: When benchmarked
using a (1 − AUC)−1 metric, MOD outperformed previous methods (template-fit, deconvolution,
and Bayesian methods) by an average factor of 3.13 for in vivo data sets, but
showed comparable (template-fit, deconvolution) or higher (Bayesian) computational
efficacy.\r\nConclusions: MOD may become an important new tool for large-scale,
real-time analysis of synaptic activity."

text: 'AMPA receptors (AMPARs) mediate the majority of excitatory transmission in
the brain and enable the synaptic plasticity that underlies learning1. A diverse
array of AMPAR signalling complexes are established by receptor auxiliary subunits,
which associate with the AMPAR in various combinations to modulate trafficking,
gating and synaptic strength2. However, their mechanisms of action are poorly
understood. Here we determine cryo-electron microscopy structures of the heteromeric
GluA1–GluA2 receptor assembled with both TARP-γ8 and CNIH2, the predominant AMPAR
complex in the forebrain, in both resting and active states. Two TARP-γ8 and two
CNIH2 subunits insert at distinct sites beneath the ligand-binding domains of
the receptor, with site-specific lipids shaping each interaction and affecting
the gating regulation of the AMPARs. Activation of the receptor leads to asymmetry
between GluA1 and GluA2 along the ion conduction path and an outward expansion
of the channel triggers counter-rotations of both auxiliary subunit pairs, promoting
the active-state conformation. In addition, both TARP-γ8 and CNIH2 pivot towards
the pore exit upon activation, extending their reach for cytoplasmic receptor
elements. CNIH2 achieves this through its uniquely extended M2 helix, which has
transformed this endoplasmic reticulum-export factor into a powerful AMPAR modulator
that is capable of providing hippocampal pyramidal neurons with their integrative
synaptic properties. '

text: The hippocampal mossy fiber synapse is a key synapse of the trisynaptic circuit.
Post-tetanic potentiation (PTP) is the most powerful form of plasticity at this
synaptic connection. It is widely believed that mossy fiber PTP is an entirely
presynaptic phenomenon, implying that PTP induction is input-specific, and requires
neither activity of multiple inputs nor stimulation of postsynaptic neurons. To
directly test cooperativity and associativity, we made paired recordings between
single mossy fiber terminals and postsynaptic CA3 pyramidal neurons in rat brain
slices. By stimulating non-overlapping mossy fiber inputs converging onto single
CA3 neurons, we confirm that PTP is input-specific and non-cooperative. Unexpectedly,
mossy fiber PTP exhibits anti-associative induction properties. EPSCs show only
minimal PTP after combined pre- and postsynaptic high-frequency stimulation with
intact postsynaptic Ca2+ signaling, but marked PTP in the absence of postsynaptic
spiking and after suppression of postsynaptic Ca2+ signaling (10 mM EGTA). PTP
is largely recovered by inhibitors of voltage-gated R- and L-type Ca2+ channels,
group II mGluRs, and vacuolar-type H+-ATPase, suggesting the involvement of retrograde
vesicular glutamate signaling. Transsynaptic regulation of PTP extends the repertoire
of synaptic computations, implementing a brake on mossy fiber detonation and a
“smart teacher” function of hippocampal mossy fiber synapses.

text: AMPA receptor (AMPAR) abundance and positioning at excitatory synapses regulates
the strength of transmission. Changes in AMPAR localisation can enact synaptic
plasticity, allowing long-term information storage, and is therefore tightly controlled.
Multiple mechanisms regulating AMPAR synaptic anchoring have been described, but
with limited coherence or comparison between reports, our understanding of this
process is unclear. Here, combining synaptic recordings from mouse hippocampal
slices and super-resolution imaging in dissociated cultures, we compare the contributions
of three AMPAR interaction domains controlling transmission at hippocampal CA1
synapses. We show that the AMPAR C-termini play only a modulatory role, whereas
the extracellular N-terminal domain (NTD) and PDZ interactions of the auxiliary
subunit TARP γ8 are both crucial, and each is sufficient to maintain transmission.
Our data support a model in which γ8 accumulates AMPARs at the postsynaptic density,
where the NTD further tunes their positioning. This interplay between cytosolic
(TARP γ8) and synaptic cleft (NTD) interactions provides versatility to regulate
synaptic transmission and plasticity.

text: Rigorous investigation of synaptic transmission requires analysis of unitary
synaptic events by simultaneous recording from presynaptic terminals and postsynaptic
target neurons. However, this has been achieved at only a limited number of model
synapses, including the squid giant synapse and the mammalian calyx of Held. Cortical
presynaptic terminals have been largely inaccessible to direct presynaptic recording,
due to their small size. Here, we describe a protocol for improved subcellular
patch-clamp recording in rat and mouse brain slices, with the synapse in a largely
intact environment. Slice preparation takes ~2 h, recording ~3 h and post hoc
morphological analysis 2 d. Single presynaptic hippocampal mossy fiber terminals
are stimulated minimally invasively in the bouton-attached configuration, in which
the cytoplasmic content remains unperturbed, or in the whole-bouton configuration,
in which the cytoplasmic composition can be precisely controlled. Paired pre–postsynaptic
recordings can be integrated with biocytin labeling and morphological analysis,
allowing correlative investigation of synapse structure and function. Paired recordings
can be obtained from mossy fiber terminals in slices from both rats and mice,
implying applicability to genetically modified synapses. Paired recordings can
also be performed together with axon tract stimulation or optogenetic activation,
allowing comparison of unitary and compound synaptic events in the same target
cell. Finally, paired recordings can be combined with spontaneous event analysis,
permitting collection of miniature events generated at a single identified synapse.
In conclusion, the subcellular patch-clamp techniques detailed here should facilitate
analysis of biophysics, plasticity and circuit function of cortical synapses in
the mammalian central nervous system.

text: Pattern separation is a fundamental brain computation that converts small
differences in input patterns into large differences in output patterns. Several
synaptic mechanisms of pattern separation have been proposed, including code expansion,
inhibition and plasticity; however, which of these mechanisms play a role in the
entorhinal cortex (EC)–dentate gyrus (DG)–CA3 circuit, a classical pattern separation
circuit, remains unclear. Here we show that a biologically realistic, full-scale
EC–DG–CA3 circuit model, including granule cells (GCs) and parvalbumin-positive
inhibitory interneurons (PV+-INs) in the DG, is an efficient pattern separator.
Both external gamma-modulated inhibition and internal lateral inhibition mediated
by PV+-INs substantially contributed to pattern separation. Both local connectivity
and fast signaling at GC–PV+-IN synapses were important for maximum effectiveness.
Similarly, mossy fiber synapses with conditional detonator properties contributed
to pattern separation. By contrast, perforant path synapses with Hebbian synaptic
plasticity and direct EC–CA3 connection shifted the network towards pattern completion.
Our results demonstrate that the specific properties of cells and synapses optimize
higher-order computations in biological networks and might be useful to improve
the deep learning capabilities of technical networks.

text: The synaptic connection from medial habenula (MHb) to interpeduncular nucleus
(IPN) is critical for emotion-related behaviors and uniquely expresses R-type
Ca2+ channels (Cav2.3) and auxiliary GABAB receptor (GBR) subunits, the K+-channel
tetramerization domain-containing proteins (KCTDs). Activation of GBRs facilitates
or inhibits transmitter release from MHb terminals depending on the IPN subnucleus,
but the role of KCTDs is unknown. We therefore examined the localization and function
of Cav2.3, GBRs, and KCTDs in this pathway in mice. We show in heterologous cells
that KCTD8 and KCTD12b directly bind to Cav2.3 and that KCTD8 potentiates Cav2.3
currents in the absence of GBRs. In the rostral IPN, KCTD8, KCTD12b, and Cav2.3
co-localize at the presynaptic active zone. Genetic deletion indicated a bidirectional
modulation of Cav2.3-mediated release by these KCTDs with a compensatory increase
of KCTD8 in the active zone in KCTD12b-deficient mice. The interaction of Cav2.3
with KCTDs therefore scales synaptic strength independent of GBR activation.

text: Post-tetanic potentiation (PTP) is an attractive candidate mechanism for hippocampus-dependent
short-term memory. Although PTP has a uniquely large magnitude at hippocampal
mossy fiber-CA3 pyramidal neuron synapses, it is unclear whether it can be induced
by natural activity and whether its lifetime is sufficient to support short-term
memory. We combined in vivo recordings from granule cells (GCs), in vitro paired
recordings from mossy fiber terminals and postsynaptic CA3 neurons, and “flash
and freeze” electron microscopy. PTP was induced at single synapses and showed
a low induction threshold adapted to sparse GC activity in vivo. PTP was mainly
generated by enlargement of the readily releasable pool of synaptic vesicles,
allowing multiplicative interaction with other plasticity forms. PTP was associated
with an increase in the docked vesicle pool, suggesting formation of structural
“pool engrams.” Absence of presynaptic activity extended the lifetime of the potentiation,
enabling prolonged information storage in the hippocampal network.

text: Dentate gyrus granule cells (GCs) connect the entorhinal cortex to the hippocampal
CA3 region, but how they process spatial information remains enigmatic. To examine
the role of GCs in spatial coding, we measured excitatory postsynaptic potentials
(EPSPs) and action potentials (APs) in head-fixed mice running on a linear belt.
Intracellular recording from morphologically identified GCs revealed that most
cells were active, but activity level varied over a wide range. Whereas only ∼5%
of GCs showed spatially tuned spiking, ∼50% received spatially tuned input. Thus,
the GC population broadly encodes spatial information, but only a subset relays
this information to the CA3 network. Fourier analysis indicated that GCs received
conjunctive place-grid-like synaptic input, suggesting code conversion in single
neurons. GC firing was correlated with dendritic complexity and intrinsic excitability,
but not extrinsic excitatory input or dendritic cable properties. Thus, functional
maturation may control input-output transformation and spatial code conversion.

text: How structural and functional properties of synapses relate to each other
is a fundamental question in neuroscience. Electrophysiology has elucidated mechanisms
of synaptic transmission, and electron microscopy (EM) has provided insight into
morphological properties of synapses. Here we describe an enhanced method for
functional EM (“flash and freeze”), combining optogenetic stimulation with high-pressure
freezing. We demonstrate that the improved method can be applied to intact networks
in acute brain slices and organotypic slice cultures from mice. As a proof of
concept, we probed vesicle pool changes during synaptic transmission at the hippocampal
mossy fiber-CA3 pyramidal neuron synapse. Our findings show overlap of the docked
vesicle pool and the functionally defined readily releasable pool and provide
evidence of fast endocytosis at this synapse. Functional EM with acute slices
and slice cultures has the potential to reveal the structural and functional mechanisms
of transmission in intact, genetically perturbed, and disease-affected synapses.

text: Neurone empfangen Eingangssignale, konvertieren diese in Aktionspotenziale
und generieren schließlich Ausgangssignale auf ihren Zielzellen. Dabei sind die
zu überwindenden räumlichen Distanzen oft groß. Daher ist entscheidend, dass elektrische
Signale in Nervenzellen schnell von einem zum anderen Ort geleitet werden können.
Diese wichtige Aufgabe erfüllt das Axon, der „Ausgangsfortsatz“ der Nervenzelle.
Für die schnelle Leitung des Aktionspotenzials sind sowohl die passiven Eigenschaften
des axonalen Kabels als auch die aktiven Eigenschaften der Zellmembran von entscheidender
Bedeutung. Die Evolution bedient sich zweier Tricks, um die Leitungsgeschwindigkeit
des Aktionspotenzials zu maximieren. Der eine Trick ist die Zunahme des Axondurchmessers.
Der andere Trick ist die Ausbildung von Markscheiden. Dies führt bei nahezu gleichem
Platzbedarf zu einer Zunahme der Leistungsgeschwindigkeit um fast zwei Größenordnungen.
Die Aktionspotenzialleitung an myelinisierten Axonen erfolgt „saltatorisch“.

text: Biophysical modeling of neuronal networks helps to integrate and interpret
rapidly growing and disparate experimental datasets at multiple scales. The NetPyNE
tool (www.netpyne.org) provides both programmatic and graphical interfaces to
develop data-driven multiscale network models in NEURON. NetPyNE clearly separates
model parameters from implementation code. Users provide specifications at a high
level via a standardized declarative language, for example connectivity rules,
to create millions of cell-to-cell connections. NetPyNE then enables users to
generate the NEURON network, run efficiently parallelized simulations, optimize
and explore network parameters through automated batch runs, and use built-in
functions for visualization and analysis – connectivity matrices, voltage traces,
spike raster plots, local field potentials, and information theoretic measures.
NetPyNE also facilitates model sharing by exporting and importing standardized
formats (NeuroML and SONATA). NetPyNE is already being used to teach computational
neuroscience students and by modelers to investigate brain regions and phenomena.
