Influence of Autapses on Synchronization in Neural Networks With Chemical Synapses
Frontiers 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 ...

A brainwide atlas of synapses across the mouse life span
Science, 2020 Brain synapses through the life span Excitatory synapses connect neurons in the brain to build the circuits that enable behavior. Cizeron et al. surveyed synapses in the mouse brain from birth to old age and present the data as a community resource, the ...

Analytical and Bioanalytical Chemistry, 2006 Large-scale phosphoproteome analysis on synaptosome and preparation of post-synaptic density (PSD) were investigated. It was found that protein phosphor is a common event in the synapse, which is consistent with the presence of diverse classes of kinases and phosphatases in the synapse.

A Review of Graphene‐Based Memristive Neuromorphic Devices and Circuits
Advanced Intelligent Systems, 2023 As data processing volume increases, the limitations of traditional computers and the need for more efficient computing methods become evident. Neuromorphic computing mimics the brain's low‐power and high‐speed computations, making it crucial in the era ...

Glycobiology of the synapse [PDF]
Glycobiology, 2002 Synapses are the fundamental units of connectivity that link together the nervous system. Lectin studies from 30 years ago suggested that specific glycans are concentrated at neuromuscular synapses in the peripheral nervous system and at excitatory synapses in the brain.

Memcapacitive neural networks [PDF]
Electronics Letters 50, 141 (2014), 2013 We show that memcapacitive (memory capacitive) systems can be used as synapses in artificial neural networks. As an example of our approach, we discuss the architecture of an integrate-and-fire neural network based on memcapacitive synapses. Moreover, we demonstrate that the spike-timing-dependent plasticity can be simply realized with some of these ...

FEBS Open Bio, EarlyView.Two biomarkers of Alzheimer's disease, amyloid β‐peptide (Aβ) and tau, induce the transformation of U‐251 and other glioblastoma cell lines into neurotoxic A1‐like reactive astrocytes. This transformation is produced by cytokines and is followed by upregulation of PMCA activity and isoform expression, and is closely associated with inflammation, as ...

A CMOS Spiking Neuron for Dense Memristor-Synapse Connectivity for Brain-Inspired Computing [PDF]
, 2015 Neuromorphic systems that densely integrate CMOS spiking neurons and nano-scale memristor synapses open a new avenue of brain-inspired computing. Existing silicon neurons have molded neural biophysical dynamics but are incompatible with memristor ...
