The implication of a diversity of non-neuronal cells in disorders affecting brain networks

open access: yesFrontiers in Cellular Neuroscience, 2022
In the central nervous system (CNS) neurons are classically considered the functional unit of the brain. Analysis of the physical connections and co-activation of neurons, referred to as structural and functional connectivity, respectively, is a metric ...

Rostral and caudal basolateral amygdala engage distinct circuits in the prelimbic and infralimbic prefrontal cortex

open access: yeseLife, 2022
Connections from the basolateral amygdala (BLA) to medial prefrontal cortex (PFC) regulate memory and emotion and become disrupted in neuropsychiatric disorders.

Spatial representation of temporal information through spike timing dependent plasticity [PDF]

open access: yes, 2003
We suggest a mechanism based on spike time dependent plasticity (STDP) of synapses to store, retrieve and predict temporal sequences. The mechanism is demonstrated in a model system of simplified integrate-and-fire type neurons densely connected by STDP ...

Associative memory neurons of encoding multi-modal signals are recruited by neuroligin-3-mediated new synapse formation

open access: yeseLife, 2023
The joint storage and reciprocal retrieval of learnt associated signals are presumably encoded by associative memory cells. In the accumulation and enrichment of memory contents in lifespan, a signal often becomes a core signal associatively shared for ...

Homogeneous Spiking Neuromorphic System for Real-World Pattern Recognition [PDF]

open access: yes, 2015
A neuromorphic chip that combines CMOS analog spiking neurons and memristive synapses offers a promising solution to brain-inspired computing, as it can provide massive neural network parallelism and density.

Neurons Communication in the Hippocampus of Field CA3 of the White Rat Brain after Acute ischemia

open access: yesОбщая реаниматология, 2018
The aim of this study was to compare the pyramidal neurons, their processes and synapses in the stratum lucidum, stratum radiatum and stratum lacunosum of the molecular layer of the field CA3 of the hippocampus of the brain of white rats in the normal ...

Neurofilament Levels in Dendritic Spines Associate with Synaptic Status

open access: yesCells, 2023
Neurofilaments are one of the main cytoskeletal components in neurons; they can be found in the form of oligomers at pre- and postsynapses. How their presence is regulated at the postsynapse remains largely unclear.

Neuromuscular synapse [PDF]

open access: yesBiochemistry and Molecular Biology Education, 2009
AbstractDiverse biological data may be used to create illustrations of molecules in their cellular context. I describe the scientific results that support a recent textbook illustration of the neuromuscular synapse. The image magnifies a portion of the synapse at one million times, showing the location and the form of individual macromolecules. Results

A population of immature cerebellar parallel fibre synapses are insensitive to adenosine but are inhibited by hypoxia [PDF]

open access: yes, 2011
The purine adenosine plays an important role in a number of physiological and pathological processes and is neuroprotective during hypoxia and ischemia.

Influence of Autapses on Synchronization in Neural Networks With Chemical Synapses

open access: yesFrontiers in Systems Neuroscience, 2020
A great deal of research has been devoted on the investigation of neural dynamics in various network topologies. However, only a few studies have focused on the influence of autapses, synapses from a neuron onto itself via closed loops, on neural ...
