Developmental alterations in N-methyl-D-aspartate (NMDA)-stimulated[3H]norepinephrine release from rat brain cortical and hippocampal slices were studied. NMDA (10-1000 microM) resulted in a concentration-dependent increase in [3H]norepinephrine…
The effects of phenobarbital, phenytoin, and valproic acid on pharmacologically isolated NMDA-EPSP, AMPA-EPSP, and GABA-IPSPs were examined in rat hippocampal slices. Phenobarbital (0.05 mg/ml) had no effect on the NMDA-EPSP, but decreased the slope…
We previously reported that an N-methyl-D-aspartate receptor-independent component of long-term potentiation with an apparent delayed onset can be induced in area CA1 of the hippocampus. Here we show that some but not all of this delay in onset can…
