  text: 'Synaptotagmin 7 (Syt7) is thought to be a Ca2+ sensor that mediates asynchronous
    transmitter release and facilitation at synapses. However, Syt7 is strongly expressed
    in fast-spiking, parvalbumin-expressing GABAergic interneurons, and the output
    synapses of these neurons produce only minimal asynchronous release and show depression
    rather than facilitation. To resolve this apparent contradiction, we examined
    the effects of genetic elimination of Syt7 on synaptic transmission at the GABAergic
    basket cell (BC)-Purkinje cell (PC) synapse in cerebellum. Our results indicate
    that at the BC-PC synapse, Syt7 contributes to asynchronous release, pool replenishment,
    and facilitation. In combination, these three effects ensure efficient transmitter
    release during high-frequency activity and guarantee frequency independence of
    inhibition. Our results identify a distinct function of Syt7: ensuring the efficiency
    of high-frequency inhibitory synaptic transmission'

  text: Synaptotagmin 7 (Syt7) was originally identified as a slow Ca2+ sensor for
    lysosome fusion, but its function at fast synapses is controversial. The paper
    by Luo and Südhof (2017) in this issue of Neuron shows that at the calyx of Held
    in the auditory brainstem Syt7 triggers asynchronous release during stimulus trains,
    resulting in reliable and temporally precise high-frequency transmission. Thus,
    a slow Ca2+ sensor contributes to the fast signaling properties of the calyx synapse.

  text: Hemolysis drives susceptibility to bacterial infections and predicts poor
    outcome from sepsis. These detrimental effects are commonly considered to be a
    consequence of heme-iron serving as a nutrient for bacteria. We employed a Gram-negative
    sepsis model and found that elevated heme levels impaired the control of bacterial
    proliferation independently of heme-iron acquisition by pathogens. Heme strongly
    inhibited phagocytosis and the migration of human and mouse phagocytes by disrupting
    actin cytoskeletal dynamics via activation of the GTP-binding Rho family protein
    Cdc42 by the guanine nucleotide exchange factor DOCK8. A chemical screening approach
    revealed that quinine effectively prevented heme effects on the cytoskeleton,
    restored phagocytosis and improved survival in sepsis. These mechanistic insights
    provide potential therapeutic targets for patients with sepsis or hemolytic disorders.

    burst activity in dentate gyrus granule cells is required for detonation. Whether
    single unitary excitatory postsynaptic potentials (EPSPs) trigger spikes in CA3
    neurons remains unknown. Mossy fiber synapses exhibit both pronounced short-term
    facilitation and uniquely large post-tetanic potentiation (PTP). We tested whether
    PTP could convert mossy fiber synapses from subdetonator into detonator mode,
    using a recently developed method to selectively and noninvasively stimulate individual
    presynaptic terminals in rat brain slices. Unitary EPSPs failed to initiate a
    spike in CA3 neurons under control conditions, but reliably discharged them after
    induction of presynaptic short-term plasticity. Remarkably, PTP switched mossy
    fiber synapses into full detonators for tens of seconds. Plasticity-dependent
    detonation may be critical for efficient coding, storage, and recall of information
    in the granule cell–CA3 cell network.

  text: "The hippocampal CA3 region plays a key role in learning and memory. Recurrent
    CA3–CA3\r\nsynapses are thought to be the subcellular substrate of pattern completion.
    However, the\r\nsynaptic mechanisms of this network computation remain enigmatic.
    To investigate these mechanisms, we combined functional connectivity analysis
    with network modeling.\r\nSimultaneous recording fromup to eight CA3 pyramidal
    neurons revealed that connectivity was sparse, spatially uniform, and highly enriched
    in disynaptic motifs (reciprocal, convergence,divergence, and chain motifs). Unitary
    connections were composed of one or two synaptic contacts, suggesting efficient
    use of postsynaptic space. Real-size modeling indicated that CA3 networks with
    sparse connectivity, disynaptic motifs, and single-contact connections robustly
    generated pattern completion.Thus, macro- and microconnectivity contribute to
    efficient\r\nmemory storage and retrieval in hippocampal networks."

  text: CA3 pyramidal neurons are thought to pay a key role in memory storage and
    pattern completion by activity-dependent synaptic plasticity between CA3-CA3 recurrent
    excitatory synapses. To examine the induction rules of synaptic plasticity at
    CA3-CA3 synapses, we performed whole-cell patch-clamp recordings in acute hippocampal
    slices from rats (postnatal 21-24 days) at room temperature. Compound excitatory
    postsynaptic potentials (ESPSs) were recorded by tract stimulation in stratum
    oriens in the presence of 10 µM gabazine. High-frequency stimulation (HFS) induced
    N-methyl-D-aspartate (NMDA) receptor-dependent long-term potentiation (LTP). Although
    LTP by HFS did not requier postsynaptic spikes, it was blocked by Na+-channel
    blockers suggesting that local active processes (e.g.) dendritic spikes) may contribute
    to LTP induction without requirement of a somatic action potential (AP). We next
    examined the properties of spike timing-dependent plasticity (STDP) at CA3-CA3
    synapses. Unexpectedly, low-frequency pairing of EPSPs and backpropagated action
    potentialy (bAPs) induced LTP, independent of temporal order. The STDP curve was
    symmetric and broad, with a half-width of ~150 ms. Consistent with these specific
    STDP induction properties, post-presynaptic sequences led to a supralinear summation
    of spine [Ca2+] transients. Furthermore, in autoassociative network models, storage
    and recall was substantially more robust with symmetric than with asymmetric STDP
    rules. In conclusion, we found associative forms of LTP at CA3-CA3 recurrent collateral
    synapses with distinct induction rules. LTP induced by HFS may be associated with
    dendritic spikes. In contrast, low frequency pairing of pre- and postsynaptic
    activity induced LTP only if EPSP-AP were temporally very close. Together, these
    induction mechanisms of synaptiic plasticity may contribute to memory storage
    in the CA3-CA3 microcircuit at different ranges of activity.

  text: CA3–CA3 recurrent excitatory synapses are thought to play a key role in memory
    storage and pattern completion. Whether the plasticity properties of these synapses
    are consistent with their proposed network functions remains unclear. Here, we
    examine the properties of spike timing-dependent plasticity (STDP) at CA3–CA3
    synapses. Low-frequency pairing of excitatory postsynaptic potentials (EPSPs)
    and action potentials (APs) induces long-term potentiation (LTP), independent
    of temporal order. The STDP curve is symmetric and broad (half-width ~150 ms).
    Consistent with these STDP induction properties, AP–EPSP sequences lead to supralinear
    summation of spine [Ca2+] transients. Furthermore, afterdepolarizations (ADPs)
    following APs efficiently propagate into dendrites of CA3 pyramidal neurons, and
    EPSPs summate with dendritic ADPs. In autoassociative network models, storage
    and recall are more robust with symmetric than with asymmetric STDP rules. Thus,
    a specialized STDP induction rule allows reliable storage and recall of information
    in the hippocampal CA3 network.

  text: ATP released from neurons and astrocytes during neuronal activity or under
    pathophysiological circumstances is able to influence information flow in neuronal
    circuits by activation of ionotropic P2X and metabotropic P2Y receptors and subsequent
    modulation of cellular excitability, synaptic strength, and plasticity. In the
    present paper we review cellular and network effects of P2Y receptors in the brain.
    We show that P2Y receptors inhibit the release of neurotransmitters, modulate
    voltage- and ligand-gated ion channels, and differentially influence the induction
    of synaptic plasticity in the prefrontal cortex, hippocampus, and cerebellum.
    The findings discussed here may explain how P2Y1 receptor activation during brain
    injury, hypoxia, inflammation, schizophrenia, or Alzheimer's disease leads to
    an impairment of cognitive processes. Hence, it is suggested that the blockade
    of P2Y1 receptors may have therapeutic potential against cognitive disturbances
    in these states.

  text: The hippocampus plays a key role in learning and memory. Previous studies
    suggested that the main types of principal neurons, dentate gyrus granule cells
    (GCs), CA3 pyramidal neurons, and CA1 pyramidal neurons, differ in their activity
    pattern, with sparse firing in GCs and more frequent firing in CA3 and CA1 pyramidal
    neurons. It has been assumed but never shown that such different activity may
    be caused by differential synaptic excitation. To test this hypothesis, we performed
    high-resolution whole-cell patch-clamp recordings in anesthetized rats in vivo.
    In contrast to previous in vitro data, both CA3 and CA1 pyramidal neurons fired
    action potentials spontaneously, with a frequency of ∼3–6 Hz, whereas GCs were
    silent. Furthermore, both CA3 and CA1 cells primarily fired in bursts. To determine
    the underlying mechanisms, we quantitatively assessed the frequency of spontaneous
    excitatory synaptic input, the passive membrane properties, and the active membrane
    characteristics. Surprisingly, GCs showed comparable synaptic excitation to CA3
    and CA1 cells and the highest ratio of excitation versus hyperpolarizing inhibition.
    Thus, differential synaptic excitation is not responsible for differences in firing.
    Moreover, the three types of hippocampal neurons markedly differed in their passive
    properties. While GCs showed the most negative membrane potential, CA3 pyramidal
    neurons had the highest input resistance and the slowest membrane time constant.
    The three types of neurons also differed in the active membrane characteristics.
    GCs showed the highest action potential threshold, but displayed the largest gain
    of the input-output curves. In conclusion, our results reveal that differential
    firing of the three main types of hippocampal principal neurons in vivo is not
    primarily caused by differences in the characteristics of the synaptic input,
    but by the distinct properties of synaptic integration and input-output transformation.

  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.

  text: 'GABAergic perisoma-inhibiting fast-spiking interneurons (PIIs) effectively
    control the activity of large neuron populations by their wide axonal arborizations.
    It is generally assumed that the output of one PII to its target cells is strong
    and rapid. Here, we show that, unexpectedly, both strength and time course of
    PII-mediated perisomatic inhibition change with distance between synaptically
    connected partners in the rodent hippocampus. Synaptic signals become weaker due
    to lower contact numbers and decay more slowly with distance, very likely resulting
    from changes in GABAA receptor subunit composition. When distance-dependent synaptic
    inhibition is introduced to a rhythmically active neuronal network model, randomly
    driven principal cell assemblies are strongly synchronized by the PIIs, leading
    to higher precision in principal cell spike times than in a network with uniform
    synaptic inhibition. '

  text: Loss-of-function mutations in the synaptic adhesion protein Neuroligin-4 are
    among the most common genetic abnormalities associated with autism spectrum disorders,
    but little is known about the function of Neuroligin-4 and the consequences of
    its loss. We assessed synaptic and network characteristics in Neuroligin-4 knockout
    mice, focusing on the hippocampus as a model brain region with a critical role
    in cognition and memory, and found that Neuroligin-4 deletion causes subtle defects
    of the protein composition and function of GABAergic synapses in the hippocampal
    CA3 region. Interestingly, these subtle synaptic changes are accompanied by pronounced
    perturbations of γ-oscillatory network activity, which has been implicated in
    cognitive function and is altered in multiple psychiatric and neurodevelopmental
    disorders. Our data provide important insights into the mechanisms by which Neuroligin-4-dependent
    GABAergic synapses may contribute to autism phenotypes and indicate new strategies
    for therapeutic approaches.

  text: Huge body of evidences demonstrated that volatile anesthetics affect the hippocampal
    neurogenesis and neurocognitive functions, and most of them showed impairment
    at anesthetic dose. Here, we investigated the effect of low dose (1.8%) sevoflurane
    on hippocampal neurogenesis and dentate gyrus-dependent learning. Neonatal rats
    at postnatal day 4 to 6 (P4-6) were treated with 1.8% sevoflurane for 6 hours.
    Neurogenesis was quantified by bromodeoxyuridine labeling and electrophysiology
    recording. Four and seven weeks after treatment, the Morris water maze and contextual-fear
    discrimination learning tests were performed to determine the influence on spatial
    learning and pattern separation. A 6-hour treatment with 1.8% sevoflurane promoted
    hippocampal neurogenesis and increased the survival of newborn cells and the proportion
    of immature granular cells in the dentate gyrus of neonatal rats. Sevoflurane-treated
    rats performed better during the training days of the Morris water maze test and
    in contextual-fear discrimination learning test. These results suggest that a
    subanesthetic dose of sevoflurane promotes hippocampal neurogenesis in neonatal
    rats and facilitates their performance in dentate gyrus-dependent learning tasks.

  text: Fast-spiking, parvalbumin-expressing GABAergic interneurons, a large proportion
    of which are basket cells (BCs), have a key role in feedforward and feedback inhibition,
    gamma oscillations and complex information processing. For these functions, fast
    propagation of action potentials (APs) from the soma to the presynaptic terminals
    is important. However, the functional properties of interneuron axons remain elusive.
    We examined interneuron axons by confocally targeted subcellular patch-clamp recording
    in rat hippocampal slices. APs were initiated in the proximal axon ∼20 μm from
    the soma and propagated to the distal axon with high reliability and speed. Subcellular
    mapping revealed a stepwise increase of Na^+ conductance density from the soma
    to the proximal axon, followed by a further gradual increase in the distal axon.
    Active cable modeling and experiments with partial channel block revealed that
    low axonal Na^+ conductance density was sufficient for reliability, but high Na^+
    density was necessary for both speed of propagation and fast-spiking AP phenotype.
    Our results suggest that a supercritical density of Na^+ channels compensates
    for the morphological properties of interneuron axons (small segmental diameter,
    extensive branching and high bouton density), ensuring fast AP propagation and
    high-frequency repetitive firing.

  text: The distance between Ca^2+ channels and release sensors determines the speed
    and efficacy of synaptic transmission. Tight &quot;nanodomain&quot; channel-sensor
    coupling initiates transmitter release at synapses in the mature brain, whereas
    loose &quot;microdomain&quot; coupling appears restricted to early developmental
    stages. To probe the coupling configuration at a plastic synapse in the mature
    central nervous system, we performed paired recordings between mossy fiber terminals
    and CA3 pyramidal neurons in rat hippocampus. Millimolar concentrations of both
    the fast Ca^2+ chelator BAPTA [1,2-bis(2-aminophenoxy)ethane- N,N, N′,N′-tetraacetic
    acid] and the slow chelator EGTA efficiently suppressed transmitter release, indicating
    loose coupling between Ca^2+ channels and release sensors. Loose coupling enabled
    the control of initial release probability by fast endogenous Ca^2+ buffers and
    the generation of facilitation by buffer saturation. Thus, loose coupling provides
    the molecular framework for presynaptic plasticity.

  text: Intracellular electrophysiological recordings provide crucial insights into
    elementary neuronal signals such as action potentials and synaptic currents. Analyzing
    and interpreting these signals is essential for a quantitative understanding of
    neuronal information processing, and requires both fast data visualization and
    ready access to complex analysis routines. To achieve this goal, we have developed
    Stimfit, a free software package for cellular neurophysiology with a Python scripting
    interface and a built-in Python shell. The program supports most standard file
    formats for cellular neurophysiology and other biomedical signals through the
    Biosig library. To quantify and interpret the activity of single neurons and communication
    between neurons, the program includes algorithms to characterize the kinetics
    of presynaptic action potentials and postsynaptic currents, estimate latencies
    between pre- and postsynaptic events, and detect spontaneously occurring events.
    We validate and benchmark these algorithms, give estimation errors, and provide
    sample use cases, showing that Stimfit represents an efficient, accessible and
    extensible way to accurately analyze and interpret neuronal signals.
