Interaction between tetanus long-term potentiation and hypoxia-induced potentiation in the rat hippocampus. J. Neurophysiol. 78: 2475-2482, 1997. The interaction between tetanus-induced long-term potentiation (LTP) and hypoxia-induced potentiation was investigated by performing extracellular recordings in the CA1 region of rat hippocampus using a two-pathway design. Hippocampal slices were plac...

Opto-Synaptic Devices Artificial optoelectronic synapses based on MoS2 field-effect transistors (FETs) have been implemented by Biying Huang, Na Li, Guangyu Zhang, and colleagues in article number 2201558. In addition to basic opto-synaptic functions interest-modulate human visual memory, background noise filtering with a high recognition accuracy ≈ 85.5% were realized integrating the sensing, ...

There is now compelling evidence that the neurodegenerative process in Alzheimer's disease (AD) begins in synapses. Loss of synaptic proteins and functional synapses in the amyloid precursor protein (APP) transgenic mouse models of AD is well established. However, what is the earliest age at which such loss of synapses occurs, and whether known markers of AD progression accelerate functional de...

Adaptations of vestibulo-ocular and optokinetic response eye movements have been studied as an experimental model of cerebellum-dependent motor learning. Several previous physiological and pharmacological studies have consistently suggested that the cerebellar flocculus (FL) Purkinje cells (P-cells) and the medial vestibular nucleus (MVN) neurons targeted by FL (FL-targeted MVN neurons) may res...

Despite extensive research, much controversy remains regarding the locus of expression of long-term potentiation (LTP) in area CA1 of the hippocampus, specifically, whether LTP is accompanied by an increase in the probability of release (p(r)) of synaptic vesicles. We have developed a novel method for assaying p(r), which utilizes the synaptic refractory period--a brief 5-6 ms period following ...

BACKGROUND Long-term potentiation (LTP), a much studied cellular model of synaptic plasticity, has not been demonstrated at synapses between primary afferent C-fibers and spinal dorsal horn (DH) neurons in mice in vivo. EphrinB-EphB receptor signaling plays important roles in synaptic connection and plasticity in the nervous system, but its role in spinal synaptic plasticity remains unclear. ...

Synapses play a critical role in memory, learning, and cognition. Their main functions include converting pre-synaptic voltage spikes to post-synaptic currents, as well scaling the input signal. Several brain-inspired architectures have been proposed emulate behavior of biological synapses. While these are useful explore properties nervous systems, challenge making biocompatible flexible circui...

We investigated long-lasting interactions that may occur between two forms of intercellular signaling: cholinergic synaptic transmission and gap junction-mediated coupling in the rat adrenal medulla. The junctional coupling between chromaffin cells was studied during reduced or blocked synaptic transmission in adrenal slices. First, cholinergic synaptic activity was reduced by pharmacological t...
