Dynamic actin filaments are required for stable long-term potentiation (LTP) in area CA1 of the hippocampus.

The hypothesis that dynamic actin filaments participate in specific aspects of synaptic plasticity was investigated at the Schaffer-collateral-CA1 pyramidal cell synapse of mouse hippocampus. Low concentrations (0.01-1 microM) of compounds that inhibit actin filament assembly were bath applied to hippocampal slices during extracellular recording of field excitatory postsynaptic potentials. Cyto...

dose 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 ...

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...

Effect of forced treadmill exercise on long-term potentiation (LTP) in the dentate gyrus of hippocampus in male rats

Introduction: Previous studies indicate that exercise influences cognitive function. Nevertheless, considering that exercise in animal study can be voluntary, or forced, effects of exercise (specially forced exercise) on learning and memory abides as a matter of controversy. The present study aimed to investigate the effects of treadmill exercise on LTP in the dentate gyrus of rats. Methods: T...

Developmental onset of long-term potentiation in area CA1 of the rat hippocampus.

Long-term potentiation (l.t.p.) was studied in area CA1 of rat hippocampal slices during development at post-natal days 1-8, 15 and 60. Tetanic stimulation at 100 Hz for 1 s was delivered to the fibres in stratum radiatum and the time course of potentiation was recorded in stratum pyramidale for 20 min after tetanus. L.t.p. was measured at 20 min post-tetanus as an increase in the amplitude of ...
