The aim of this study was to examine: (1) whether long-term potentiation (LTP) can be induced in slices from adult rat visual cortex under conditions where inhibition is not antagonized, and (2) the role of N-methyl-D-aspartate (NMDA) receptors in…
Conditioning stimulation applied to afferent fibers in stratum radiatum or stratum oriens of hippocampal area CA1 produced heterosynaptic, posttetanic depression (PTD) of excitatory postsynaptic potentials (EPSPs). PTD amounted to a
