abstract：:Stimulation of the Schaffer collateral projection to the CA1 region in rat hippocampal slices at 1 Hz for 15 min produced a N-methyl-D-aspartate (NMDA) receptor-dependent long-term depression (LTD) of synaptic responses and, when given after tetanic stimulation, reversed long-term potentiation (LTP). Both LTD and the ...

The short phase of sensory memory corresponds to the temporal window of integration (TWI) which integrates the neighboring sounds into a unitary event. We measured the magnetic MMN (MMNm) and the disc...
