text: Poxviruses are among the largest double-stranded DNA viruses, with members
such as variola virus, monkeypox virus and the vaccination strain vaccinia virus
(VACV). Knowledge about the structural proteins that form the viral core has remained
sparse. While major core proteins have been annotated via indirect experimental
evidence, their structures have remained elusive and they could not be assigned
to individual core features. Hence, which proteins constitute which layers of
the core, such as the palisade layer and the inner core wall, has remained enigmatic.
Here we show, using a multi-modal cryo-electron microscopy (cryo-EM) approach
in combination with AlphaFold molecular modeling, that trimers formed by the cleavage
product of VACV protein A10 are the key component of the palisade layer. This
allows us to place previously obtained descriptions of protein interactions within
the core wall into perspective and to provide a detailed model of poxvirus core
architecture. Importantly, we show that interactions within A10 trimers are likely
generalizable over members of orthopox- and parapoxviruses.

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: 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: 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: 'Background: Standards have become available to share semantically encoded
vital parameters from medical devices, as required for example by personal healthcare
records. Standardised sharing of biosignal data largely remains open. Objectives:
The goal of this work is to explore available biosignal file format and data exchange
standards and profiles, and to conceptualise end-To-end solutions. Methods: The
authors reviewed and discussed available biosignal file format standards with
other members of international standards development organisations (SDOs). Results:
A raw concept for standards based acquisition, storage, archiving and sharing
of biosignals was developed. The GDF format may serve for storing biosignals.
Signals can then be shared using FHIR resources and may be stored on FHIR servers
or in DICOM archives, with DICOM waveforms as one possible format. Conclusion:
Currently a group of international SDOs (e.g. HL7, IHE, DICOM, IEEE) is engaged
in intensive discussions. This discussion extends existing work that already was
adopted by large implementer communities. The concept presented here only reports
the current status of the discussion in Austria. The discussion will continue
internationally, with results to be expected over the coming years.'

text: "The main goal of the SCP-ECG standard is to address ECG data and related
metadata structuring, semantics and syntax, with the objective of facilitating
interoperability and thus supporting and promoting the exchange of the relevant
information for unary and serial ECG diagnosis. Starting with version V3.0, the
standard now also provides support for the storage of continuous, long-term ECG
recordings and affords a repository for selected ECG sequences and the related
metadata to accommodate stress tests, drug trials and protocol-based ECG recordings.
The global and per-lead measurements sections have been extended and three new
sections have been introduced for storing beat-by-beat and/or spike-by-spike measurements\r\nand
annotations. The used terminology and the provided measurements and annotations
have been harmonized with the ISO/IEEE 11073-10102 Annotated ECG standard. Emphasis
has also been put on harmonizing the Universal Statement Codes with the CDISC
and the categorized AHA statement codes and similarly the drug and implanted devices
codes with the ATC and NASPE/BPEG codes. "

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: To search for a target in a complex environment is an everyday behavior that
ends with finding the target. When we search for two identical targets, however,
we must continue the search after finding the first target and memorize its location.
We used fixation-related potentials to investigate the neural correlates of different
stages of the search, that is, before and after finding the first target. Having
found the first target influenced subsequent distractor processing. Compared to
distractor fixations before the first target fixation, a negative shift was observed
for three subsequent distractor fixations. These results suggest that processing
a target in continued search modulates the brain's response, either transiently
by reflecting temporary working memory processes or permanently by reflecting
working memory retention.

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.

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.
