Indium–Gallium–Zinc–Oxide Schottky Synaptic Transistors for Silent Synapse Conversion Emulation
IEEE Electron Device Letters, 2019Silent synapses play an important role in synaptic plasticity and the nervous system development. In this letter, indium–gallium–zinc–oxide (IGZO) Schottky electric-double-layer transistors were proposed for silent synapse conversion emulation. Silent to

Silent Synapse Unsilencing in Hippocampal CA1 Neurons for Associative Fear Memory Storage.
Cerebral Cortex, 2018Clarifying learning-induced synaptic plasticity in hippocampal circuits is critical for understanding hippocampal mechanisms of memory acquisition and storage. Many in vitro studies have demonstrated learning-associated plasticity at hippocampal synapses.

Activating Silent Synapses in Sulfurized Indium Selenide for Neuromorphic Computing.
ACS Applied Materials and Interfaces, 2021The transformation from silent to functional synapses is accompanied by the evolutionary process of human brain development and is essential to hardware implementation of the evolutionary artificial neural network but remains a challenge for mimicking ...

Silent synapses in neuromuscular junction development
Journal of Neuroscience Research, 2010AbstractIn the last few years, evidence has been found to suggest that some synaptic contacts become silent but can be functionally recruited before they completely retract during postnatal synapse elimination in muscle. The physiological mechanism of developmental synapse elimination may be better understood by studying this synapse recruitment.

Silent glutamatergic synapses in the mammalian brain
Canadian Journal of Physiology and Pharmacology, 1999Excitatory synaptic transmission in the mammalian brain is mediated primarily by α-amino-3-hydroxy-5-methylisoxazolepropionic acid (AMPA) and N-methyl-D-aspartate (NMDA) receptors that are thought to be co-localized at individual synapses. However, recent electrophysiological and anatomical data suggest that the synaptic localization of AMPA and NMDA ...

Silent Synapses in Developing Cerebellar Granule Neurons
Journal of Neurophysiology, 2002Silent synapses are excitatory synapses endowed exclusively with N-methyl-d-aspartate (NMDA) responses that have been proposed to acquire α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) responses during development and after long-term potentiation (LTP).

Postsynaptic silent synapses: evidence and mechanisms
Neuropharmacology, 2003In this review I discuss the evidence that some glutamatergic synapses exist that lack surface-expressed postsynaptic AMPA receptors (AMPARs) but contain NMDA receptors opposed to a functional release site. I have summarised the electrophysiological, anatomical and cell biological evidence for such postsynaptically silent synapses, and data that ...

Compartment-Specific Neurexin Nanodomains Orchestrate Tripartite Synapse Assembly
, 2020At tripartite synapses, astrocytes enmesh synaptic contacts, but how astrocytes contribute to the formation, maturation and plasticity of synapses remains elusive. Here we show that both astrocytes and neurons abundantly express neurexin-1, a presynaptic

Activity‐Dependent Recruitment of Silent Synapsesa
Annals of the New York Academy of Sciences, 1991At the crayfish neuromuscular junction, a long-lasting enhancement of synaptic transmission can be induced by tetanic stimulation of 10-20 Hz for several minutes. The long-lasting enhancement is presynaptic in origin, because quantal content increases but not quantal size, and is not dependent upon broadening or enlargement of the presynaptic action ...
