Fluoride-stimulated adenylate cyclase activity in rat brain following chronic treatment with psychotropic drugs.

abstract：:In general, N-methyl-D-aspartate (NMDA) receptor antagonists inhibit learning and long term potentiation (LTP). However, it has been suggested that direct tonic, i.e. non-temporal, activation of NMDA receptors, in contrast to learning, may lead to an increase in synaptic "noise" and, in turn, to a loss of association ...
