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 mediated by nmda receptors (25- to 50-hz tetanus) and ltp mediated by voltage-dependent calcium channels (200-hz tetanus). |
