Long-term potentiation (LTP) and long-term depression (LTD) are calcium-dependent forms of synaptic plasticity observed in area CA1 of the hippocampus. Low-frequency tetani (1-5 Hz) activates protein phosphatases to induce LTD, whereas high-frequency…

The two forms of long-term potentiation (LTP) and one form of long-term depression (LTD) in hippocampal area CA1 are induced by different afferent tetani: LTD is induced by a 3- to 5-Hz tetanus, whereas higher frequencies are necessary for LTP…

We studied the ontogeny of inhibitory and excitatory processes in the rat dentate gyrus by examining paired-pulse plasticity in the hippocampal slice preparation. The mature dentate gyrus produces characteristic paired-pulse responses across a wide…

There are 3 known forms of synaptic plasticity at CNS synapses: long-term potentiation (LTP) mediated by NMDA receptor activation, LTP mediated by voltage-dependent calcium channel (VDCC) activation, and long-term depression (LTD) mediated by the…
