text: Spontaneous postsynaptic currents (PSCs) provide key information about the
mechanisms of synaptic transmission and the activity modes of neuronal networks.
However, detecting spontaneous PSCs in vitro and in vivo has been challenging,
because of the small amplitude, the variable kinetics, and the undefined time
of generation of these events. Here, we describe a, to our knowledge, new method
for detecting spontaneous synaptic events by deconvolution, using a template that
approximates the average time course of spontaneous PSCs. A recorded PSC trace
is deconvolved from the template, resulting in a series of delta-like functions.
The maxima of these delta-like events are reliably detected, revealing the precise
onset times of the spontaneous PSCs. Among all detection methods, the deconvolution-based
method has a unique temporal resolution, allowing the detection of individual
events in high-frequency bursts. Furthermore, the deconvolution-based method has
a high amplitude resolution, because deconvolution can substantially increase
the signal/noise ratio. When tested against previously published methods using
experimental data, the deconvolution-based method was superior for spontaneous
PSCs recorded in vivo. Using the high-resolution deconvolution-based detection
algorithm, we show that the frequency of spontaneous excitatory postsynaptic currents
in dentate gyrus granule cells is 4.5 times higher in vivo than in vitro.

text: "The coupling between presynaptic Ca^(2+) channels and Ca^(2+) sensors of
exocytosis is a key determinant of synaptic transmission. Evoked release from
parvalbumin (PV)-expressing interneurons is triggered by nanodomain coupling of
P/Q-type Ca^(2+) channels, whereas release from cholecystokinin (CCK)-containing
interneurons is generated by microdomain coupling of N-type channels. Nanodomain
coupling has several functional advantages, including speed and efficacy of transmission.
One potential disadvantage is that stochastic\r\nopening of presynaptic Ca^(2+)
channels may trigger spontaneous transmitter release. We addressed this possibility
in rat hippocampal\r\ngranule cells, which receive converging inputs from different
inhibitory sources. Both reduction of extracellular Ca^(2+) concentration and
the unselective Ca^(2+) channel blocker Cd^(2+) reduced the frequency of miniature
IPSCs (mIPSCs) in granule cells by ~50%, suggesting that the opening of presynaptic
Ca^(2+) channels contributes to spontaneous release. Application of the selective
P/Q-type Ca^(2+) channel blocker\r\nω-agatoxin IVa had no detectable effects,
whereas both the N-type blocker ω-conotoxin GVIa and the L-type blocker nimodipine
reduced\r\nmIPSC frequency. Furthermore, both the fast Ca^(2+) chelator BAPTA-AM
and the slow chelator EGTA-AM reduced the mIPSC frequency,\r\nsuggesting that
Ca^(2+)-dependent spontaneous release is triggered by microdomain rather than
nanodomain coupling. The CB_(1) receptor\r\nagonist WIN 55212-2 also decreased
spontaneous release; this effect was occluded by prior application of ω-conotoxin
GVIa, suggesting that a major fraction of Ca^(2+)-dependent spontaneous release
was generated at the terminals of CCK-expressing interneurons. Tonic inhibition
generated by spontaneous opening of presynaptic N- and L-type Ca^(2+) channels
may be important for hippocampal information processing.\r\n"

text: Voltage-activated Ca(2+) channels (VACCs) mediate Ca(2+) influx to trigger
action potential-evoked neurotransmitter release, but the mechanism by which Ca(2+)
regulates spontaneous transmission is unclear. We found that VACCs are the major
physiological triggers for spontaneous release at mouse neocortical inhibitory
synapses. Moreover, despite the absence of a synchronizing action potential, we
found that spontaneous fusion of a GABA-containing vesicle required the activation
of multiple tightly coupled VACCs of variable type.

text: The physical distance between presynaptic Ca2+ channels and the Ca2+ sensors
that trigger exocytosis of neurotransmitter-containing vesicles is a key determinant
of the signalling properties of synapses in the nervous system. Recent functional
analysis indicates that in some fast central synapses, transmitter release is
triggered by a small number of Ca2+ channels that are coupled to Ca2+ sensors
at the nanometre scale. Molecular analysis suggests that this tight coupling is
generated by protein–protein interactions involving Ca2+ channels, Ca2+ sensors
and various other synaptic proteins. Nanodomain coupling has several functional
advantages, as it increases the efficacy, speed and energy efficiency of synaptic
transmission.

text: 'The BCI competition IV stands in the tradition of prior BCI competitions
that aim to provide high quality neuroscientific data for open access to the scientific
community. As experienced already in prior competitions not only scientists from
the narrow field of BCI compete, but scholars with a broad variety of backgrounds
and nationalities. They include high specialists as well as students.The goals
of all BCI competitions have always been to challenge with respect to novel paradigms
and complex data. We report on the following challenges: (1) asynchronous data,
(2) synthetic, (3) multi-class continuous data, (4) sessionto-session transfer,
(5) directionally modulated MEG, (6) finger movements recorded by ECoG. As after
past competitions, our hope is that winning entries may enhance the analysis methods
of future BCIs.'

text: CA3 pyramidal neurons are important for memory formation and pattern completion
in the hippocampal network. It is generally thought that proximal synapses from
the mossy fibers activate these neurons most efficiently, whereas distal inputs
from the perforant path have a weaker modulatory influence. We used confocally
targeted patch-clamp recording from dendrites and axons to map the activation
of rat CA3 pyramidal neurons at the subcellular level. Our results reveal two
distinct dendritic domains. In the proximal domain, action potentials initiated
in the axon backpropagate actively with large amplitude and fast time course.
In the distal domain, Na+ channel–mediated dendritic spikes are efficiently initiated
by waveforms mimicking synaptic events. CA3 pyramidal neuron dendrites showed
a high Na+-to-K+ conductance density ratio, providing ideal conditions for active
backpropagation and dendritic spike initiation. Dendritic spikes may enhance the
computational power of CA3 pyramidal neurons in the hippocampal network.

text: 'CA3 pyramidal neurons are important for memory formation and pattern completion
in the hippocampal network. These neurons receive multiple excitatory inputs from
numerous sources. Therefore, the rules of spatiotemporal integration of multiple
synaptic inputs and propagation of action potentials are important to understand
how CA3 neurons contribute to higher brain functions at cellular level. By using
confocally targeted patch-clamp recording techniques, we investigated the biophysical
properties of rat CA3 pyramidal neuron dendrites. We found two distinct dendritic
domains critical for action potential initiation and propagation: In the proximal
domain, action potentials initiated in the axon backpropagate actively with large
amplitude and fast time course. In the distal domain, Na+-channel mediated dendritic
spikes are efficiently evoked by local dendritic depolarization or waveforms mimicking
synaptic events. These findings can be explained by a high Na+-to-K+ conductance
density ratio of CA3 pyramidal neuron dendrites. The results challenge the prevailing
view that proximal mossy fiber inputs activate CA3 pyramidal neurons more efficiently
than distal perforant inputs by showing that the distal synapses trigger a different
form of activity represented by dendritic spikes. The high probability of dendritic
spike initiation in the distal area may enhance the computational power of CA3
pyramidal neurons in the hippocampal network. '

text: Parvalbumin is thought to act in a manner similar to EGTA, but how a slow
Ca2+ buffer affects nanodomain-coupling regimes at GABAergic synapses is unclear.
Direct measurements of parvalbumin concentration and paired recordings in rodent
hippocampus and cerebellum revealed that parvalbumin affects synaptic dynamics
only when expressed at high levels. Modeling suggests that, in high concentrations,
parvalbumin may exert BAPTA-like effects, modulating nanodomain coupling via competition
with local saturation of endogenous fixed buffers.

text: Rab3 interacting molecules (RIMs) are highly enriched in the active zones
of presynaptic terminals. It is generally thought that they operate as effectors
of the small G protein Rab3. Three recent papers, by Han et al. (this issue of
Neuron), Deng et al. (this issue of Neuron), and Kaeser et al. (a recent issue
of Cell), shed new light on the functional role of RIM in presynaptic terminals.
First, RIM tethers Ca2+ channels to active zones. Second, RIM contributes to priming
of synaptic vesicles by interacting with another presynaptic protein, Munc13.

text: 'Spontaneous release of glutamate is important for maintaining synaptic strength
and controlling spike timing in the brain. Mechanisms regulating spontaneous exocytosis
remain poorly understood. Extracellular calcium concentration ([Ca2+]o) regulates
Ca2+ entry through voltage-activated calcium channels (VACCs) and consequently
is a pivotal determinant of action potential-evoked vesicle fusion. Extracellular
Ca 2+ also enhances spontaneous release, but via unknown mechanisms. Here we report
that external Ca2+ triggers spontaneous glutamate release more weakly than evoked
release in mouse neocortical neurons. Blockade of VACCs has no effect on the spontaneous
release rate or its dependence on [Ca2+]o. Intracellular [Ca2+] slowly increases
in a minority of neurons following increases in [Ca2+]o. Furthermore, the enhancement
of spontaneous release by extracellular calcium is insensitive to chelation of
intracellular calcium by BAPTA. Activation of the calcium-sensing receptor (CaSR),
a G-protein-coupled receptor present in nerve terminals, by several specific agonists
increased spontaneous glutamate release. The frequency of spontaneous synaptic
transmission was decreased in CaSR mutant neurons. The concentration-effect relationship
for extracellular calcium regulation of spontaneous release was well described
by a combination of CaSR-dependent and CaSR-independent mechanisms. Overall these
results indicate that extracellular Ca2+ does not trigger spontaneous glutamate
release by simply increasing calcium influx but stimulates CaSR and thereby promotes
resting spontaneous glutamate release. '

text: 'BioSig is an open source software library for biomedical signal processing.
The aim of the BioSig project is to foster research in biomedical signal processing
by providing free and open source software tools for many different application
areas. Some of the areas where BioSig can be employed are neuroinformatics, brain-computer
interfaces, neurophysiology, psychology, cardiovascular systems, and sleep research.
Moreover, the analysis of biosignals such as the electroencephalogram (EEG), electrocorticogram
(ECoG), electrocardiogram (ECG), electrooculogram (EOG), electromyogram (EMG),
or respiration signals is a very relevant element of the BioSig project. Specifically,
BioSig provides solutions for data acquisition, artifact processing, quality control,
feature extraction, classification, modeling, and data visualization, to name
a few. In this paper, we highlight several methods to help students and researchers
to work more efficiently with biomedical signals. '

text: Long-term depression (LTD) is a form of synaptic plasticity that may contribute
to information storage in the central nervous system. Here we report that LTD
can be elicited in layer 5 pyramidal neurons of the rat prefrontal cortex by pairing
low frequency stimulation with a modest postsynaptic depolarization. The induction
of LTD required the activation of both metabotropic glutamate receptors of the
mGlu1 subtype and voltage-sensitive Ca(2+) channels (VSCCs) of the T/R, P/Q and
N types, leading to the stimulation of intracellular inositol trisphosphate (IP3)
receptors by IP3 and Ca(2+). The subsequent release of Ca(2+) from intracellular
stores activated the protein phosphatase cascade involving calcineurin and protein
phosphatase 1. The activation of purinergic P2Y(1) receptors blocked LTD. This
effect was prevented by P2Y(1) receptor antagonists and was absent in mice lacking
P2Y(1) but not P2Y(2) receptors. We also found that activation of P2Y(1) receptors
inhibits Ca(2+) transients via VSCCs in the apical dendrites and spines of pyramidal
neurons. In addition, we show that the release of ATP under hypoxia is able to
inhibit LTD by acting on postsynaptic P2Y(1) receptors. In conclusion, these data
suggest that the reduction of Ca(2+) influx via VSCCs caused by the activation
of P2Y(1) receptors by ATP is the possible mechanism for the inhibition of LTD
in prefrontal cortex.

text: A recent paper by von Engelhardt et al. identifies a novel auxiliary subunit
of native AMPARs, termedCKAMP44. Unlike other auxiliary subunits, CKAMP44 accelerates
desensitization and prolongs recovery from desensitization. CKAMP44 is highly
expressed in hippocampal dentate gyrus granule cells and decreases the paired-pulse
ratio at perforant path input synapses. Thus, both principal and auxiliary AMPAR
subunits control the time course of signaling at glutamatergic synapses.
