Application of artificial synapse based on all-inorganic perovskite memristor in neuromorphic computing

Nano Materials Science
Artificial synapse inspired by the biological brain has great potential in the field of neuromorphic computing and artificial intelligence. The memristor is an ideal artificial synaptic device with fast operation and good tolerance.

Short-term plasticity of the motor cortex compensates for bradykinesia in Parkinson’s disease

Neurobiology of Disease, 2023
Patients with Parkinson's disease (PD) show impaired short-term potentiation (STP) mechanisms in the primary motor cortex (M1). However, the role played by this neurophysiological abnormality in bradykinesia pathophysiology is unknown.

Role of mast cell- and non-mast cell-derived inflammatory mediators in immunologic induction of synaptic plasticity

Brazilian Journal of Medical and Biological Research, 1997
We have previously discovered a long-lasting enhancement of synaptic transmission in mammal autonomic ganglia caused by immunological activation of ganglionic mast cells.

SHORT-TERM CIGARETTE SMOKE EXPOSURE POTENTIATES ENDOTOXIN-INDUCED PULMONARY INFLAMMATION

Experimental Lung Research, 2007
Long-term cigarette smoke exposure is associated with chronic obstructive pulmonary disease. However, the effects of short-term smoke inhalation are less clear, because it may adversely affect the lung only if underlying disease is present. To test this hypothesis, Syrian hamsters were passively exposed to cigarette smoke for 2 hours per day over a ...

Short-term synaptic plasticity in the nociceptive thalamic-anterior cingulate pathway

Molecular Pain, 2009
Background Although the mechanisms of short- and long-term potentiation of nociceptive-evoked responses are well known in the spinal cord, including central sensitization, there has been a growing body of information on such events in the cerebral cortex.

Associative induction of short-term potentiation in rat hippocampus

, 2010
Tetanic stimulation of excitatory afferent pathways in the hippocampus can lead to long-term potentiation (LTP) of the postsynaptic response. Simultaneous tetanization of two separate but convergent afferent pathways can result in associative LTP, which exhibits a magnitude that is greater than the sum of the individual potentiations.

The Pathway-Selective Dependence of Nitric Oxide for Long-Term Potentiation in the Anterior Cingulate Cortex of Adult Mice

Biomedicines
Nitric oxide (NO) is a key diffusible messenger in the mammalian brain. It has been proposed that NO may diffuse in retrograde into presynaptic terminals, contributing to the induction of hippocampal long-term potentiation (LTP).

Short-term depression and long-term plasticity together tune sensitive range of synaptic plasticity.

PLoS Computational Biology, 2020
Synaptic efficacy is subjected to activity-dependent changes on short- and long time scales. While short-term changes decay over minutes, long-term modifications last from hours up to a lifetime and are thought to constitute the basis of learning and ...

Presenilins regulate synaptic plasticity in the perforant pathways of the hippocampus

Molecular Brain, 2023
Mutations in the Presenilin genes (PSEN1 and PSEN2) are the major cause of familial Alzheimer’s disease (AD), highlighting the importance of Presenilin (PS) in AD pathogenesis.
