text: 'The hippocampal mossy fiber synapse, formed between axons of dentate gyrus
granule cells and dendrites of CA3 pyramidal neurons, is a key synapse in the
trisynaptic circuitry of the hippocampus. Because of its comparatively large size,
this synapse is accessible to direct presynaptic recording, allowing a rigorous
investigation of the biophysical mechanisms of synaptic transmission and plasticity.
Furthermore, because of its placement in the very center of the hippocampal memory
circuit, this synapse seems to be critically involved in several higher network
functions, such as learning, memory, pattern separation, and pattern completion.
Recent work based on new technologies in both nanoanatomy and nanophysiology,
including presynaptic patch-clamp recording, paired recording, super-resolution
light microscopy, and freeze-fracture and “flash-and-freeze” electron microscopy,
has provided new insights into the structure, biophysics, and network function
of this intriguing synapse. This brings us one step closer to answering a fundamental
question in neuroscience: how basic synaptic properties shape higher network computations.'

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: 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: 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: 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: 'Fast-spiking, parvalbumin-expressing GABAergic interneurons (PV+-BCs) express
a complex machinery of rapid signaling mechanisms, including specialized voltage-gated
ion channels to generate brief action potentials (APs). However, short APs are
associated with overlapping Na+ and K+ fluxes and are therefore energetically
expensive. How the potentially vicious combination of high AP frequency and inefficient
spike generation can be reconciled with limited energy supply is presently unclear.
To address this question, we performed direct recordings from the PV+-BC axon,
the subcellular structure where active conductances for AP initiation and propagation
are located. Surprisingly, the energy required for the AP was, on average, only
∼1.6 times the theoretical minimum. High energy efficiency emerged from the combination
of fast inactivation of Na+ channels and delayed activation of Kv3-type K+ channels,
which minimized ion flux overlap during APs. Thus, the complementary tuning of
axonal Na+ and K+ channel gating optimizes both fast signaling properties and
metabolic efficiency. Hu et al. demonstrate that action potentials in parvalbumin-expressing
GABAergic interneuron axons are energetically efficient, which is highly unexpected
given their brief duration. High energy efficiency emerges from the combination
of fast inactivation of voltage-gated Na+ channels and delayed activation of Kv3
channels in the axon. '

text: Mouse chromaffin cells (MCCs) generate action potential (AP) firing that regulates
the Ca2+‐dependent release of catecholamines (CAs). Recent findings indicate that
MCCs possess a variety of spontaneous firing modes that span from the common ‘tonic‐irregular’
to the less frequent ‘burst’ firing. This latter is evident in a small fraction
of MCCs but occurs regularly when Nav1.3/1.7 channels are made less available
or when the Slo1β2‐subunit responsible for BK channel inactivation is deleted.
Burst firing causes large increases of Ca2+‐entry and potentiates CA release by
∼3.5‐fold and thus may be a key mechanism for regulating MCC function. With the
aim to uncover a physiological role for burst‐firing we investigated the effects
of acidosis on MCC activity. Lowering the extracellular pH (pHo) from 7.4 to 7.0
and 6.6 induces cell depolarizations of 10–15 mV that generate repeated bursts.
Bursts at pHo 6.6 lasted ∼330 ms, occurred at 1–2 Hz and caused an ∼7‐fold increase
of CA cumulative release. Burst firing originates from the inhibition of the pH‐sensitive
TASK‐1/TASK‐3 channels and from a 40% BK channel conductance reduction at pHo
7.0. The same pHo had little or no effect on Nav, Cav, Kv and SK channels that
support AP firing in MCCs. Burst firing of pHo 6.6 could be mimicked by mixtures
of the TASK‐1 blocker A1899 (300 nm) and BK blocker paxilline (300 nm) and could
be prevented by blocking L‐type channels by adding 3 μm nifedipine. Mixtures of
the two blockers raised cumulative CA‐secretion even more than low pHo (∼12‐fold),
showing that the action of protons on vesicle release is mainly a result of the
ionic conductance changes that increase Ca2+‐entry during bursts. Our data provide
direct evidence suggesting that MCCs respond to low pHo with sustained depolarization,
burst firing and enhanced CA‐secretion, thus mimicking the physiological response
of CCs to acute acidosis and hyperkalaemia generated during heavy exercise and
muscle fatigue.

text: Neuronal and neuroendocrine L-type calcium channels (Cav1.2, Cav1.3) open
readily at relatively low membrane potentials and allow Ca2+ to enter the cells
near resting potentials. In this way, Cav1.2 and Cav1.3 shape the action potential
waveform, contribute to gene expression, synaptic plasticity, neuronal differentiation,
hormone secretion and pacemaker activity. In the chromaffin cells (CCs) of the
adrenal medulla, Cav1.3 is highly expressed and is shown to support most of the
pacemaking current that sustains action potential (AP) firings and part of the
catecholamine secretion. Cav1.3 forms Ca2+-nanodomains with the fast inactivating
BK channels and drives the resting SK currents. These latter set the inter-spike
interval duration between consecutive spikes during spontaneous firing and the
rate of spike adaptation during sustained depolarizations. Cav1.3 plays also a
primary role in the switch from “tonic” to “burst” firing that occurs in mouse
CCs when either the availability of voltage-gated Na channels (Nav) is reduced
or the β2 subunit featuring the fast inactivating BK channels is deleted. Here,
we discuss the functional role of these “neuronlike” firing modes in CCs and how
Cav1.3 contributes to them. The open issue is to understand how these novel firing
patterns are adapted to regulate the quantity of circulating catecholamines during
resting condition or in response to acute and chronic stress.

text: Leptin is an adipokine produced by the adipose tissue regulating body weight
through its appetite-suppressing effect. Besides being expressed in the hypothalamus
and hippocampus, leptin receptors (ObRs) are also present in chromaffin cells
of the adrenal medulla. In the present study, we report the effect of leptin on
mouse chromaffin cell (MCC) functionality, focusing on cell excitability and catecholamine
secretion. Acute application of leptin (1 nm) on spontaneously firing MCCs caused
a slowly developing membrane hyperpolarization followed by complete blockade of
action potential (AP) firing. This inhibitory effect at rest was abolished by
the BK channel blocker paxilline (1 μm), suggesting the involvement of BK potassium
channels. Single-channel recordings in 'perforated microvesicles' confirmed that
leptin increased BK channel open probability without altering its unitary conductance.
BK channel up-regulation was associated with the phosphoinositide 3-kinase (PI3K)
signalling cascade because the PI3K specific inhibitor wortmannin (100 nm) fully
prevented BK current increase. We also tested the effect of leptin on evoked AP
firing and Ca2+-driven exocytosis. Although leptin preserves well-adapted AP trains
of lower frequency, APs are broader and depolarization-evoked exocytosis is increased
as a result of the larger size of the ready-releasable pool and higher frequency
of vesicle release. The kinetics and quantal size of single secretory events remained
unaltered. Leptin had no effect on firing and secretion in db-/db- mice lacking
the ObR gene, confirming its specificity. In conclusion, leptin exhibits a dual
action on MCC activity. It dampens AP firing at rest but preserves AP firing and
increases catecholamine secretion during sustained stimulation, highlighting the
importance of the adipo-adrenal axis in the leptin-mediated increase of sympathetic
tone and catecholamine release.

text: Synapsins (Syns) are an evolutionarily conserved family of presynaptic proteins
crucial for the fine-tuning of synaptic function. A large amount of experimental
evidences has shown that Syns are involved in the development of epileptic phenotypes
and several mutations in Syn genes have been associated with epilepsy in humans
and animal models. Syn mutations induce alterations in circuitry and neurotransmitter
release, differentially affecting excitatory and inhibitory synapses, thus causing
an excitation/inhibition imbalance in network excitability toward hyperexcitability
that may be a determinant with regard to the development of epilepsy. Another
approach to investigate epileptogenic mechanisms is to understand how silencing
Syn affects the cellular behavior of single neurons and is associated with the
hyperexcitable phenotypes observed in epilepsy. Here, we examined the functional
effects of antisense-RNA inhibition of Syn expression on individually identified
and isolated serotonergic cells of the Helix land snail. We found that Helix synapsin
silencing increases cell excitability characterized by a slightly depolarized
resting membrane potential, decreases the rheobase, reduces the threshold for
action potential (AP) firing and increases the mean and instantaneous firing rates,
with respect to control cells. The observed increase of Ca2+ and BK currents in
Syn-silenced cells seems to be related to changes in the shape of the AP waveform.
These currents sustain the faster spiking in Syn-deficient cells by increasing
the after hyperpolarization and limiting the Na+ and Ca2+ channel inactivation
during repetitive firing. This in turn speeds up the depolarization phase by reaching
the AP threshold faster. Our results provide evidence that Syn silencing increases
intrinsic cell excitability associated with increased Ca2+ and Ca2+-dependent
BK currents in the absence of excitatory or inhibitory inputs.
