Long-term potentiation in the CA1 hippocampus.
This reinforces the view (9) that the simple relations of quantal analysis do not necessarily hold in heterogeneous populations such as those found in the central nervous system. Addition of synapses with lower quantal size will, however, change the amplitude distribution of nonfailure responses, which was not observed in the above studies (1, 2). Nevertheless, detecting this change in distribu...
متن کاملdose dependent effect of memantine on long-term potentiation in the ca1 area of the hippocampus
introduction: generally, nmda receptor antagonists inhibit learning and long-term potentiation (ltp). however, it has been suggested that direct tonic activation of nmda receptors, in contrast to learning, may lead to an increase in synaptic “noise”. uncompetitive nmda receptor antagonist memantine can paradoxically reverse deficits in learning and synaptic plasticity, and restore ltp impaired ...
متن کاملDoxepin improves stress-impaired long-term potentiation and gene expression of BDNF in the rat hippocampus
Introduction: Stress is associated with neurological and cognitive disorders. It has been suggested that doxepin, in addition to its influence on the content of neurotransmitters, has probable neuroprotective effects as well. Therefore, the aim of this study was to investigate the effects of doxepin on synaptic plasticity and brain-derived neurotrophic factor (BDNF) gene expression in the rat h...
متن کاملP19: Long-Term Potentiation
The term synaptic plasticity points to a series of persistent changes related to the activity of synapses. Long-term potentiation (LTP) is a reflection of synaptic plasticity that has an important role in learning and memory. LTP is a long-lasting increase of synaptic activity due to enhancement of excitatory synaptic transmission after a high-frequency train of electrical stimulations. Differe...
متن کاملNeonatal exposure to novelty enhances long-term potentiation in CA1 of the rat hippocampus.
Exposing rats to an enriched environment over an extended period of time has been shown to enhance hippocampal long-term potentiation (LTP). Whether such prolonged exposure to environmental manipulation is necessary for LTP enhancement and whether the environmentally induced enhancement can persist long after the cessation of the environmental manipulation remain unknown. Using a novelty exposu...
