The mechanism of disinhibition produced by opioid peptides was studied using intracellular recording in area CA1 of rat hippocampal slices. The mu-selective opioid peptide [D-Ala2,N-Me-Phe4,Gly-ol5]-enkephalin (DAGO) reversibly depressed…
We examined the effects of GABAB receptor activation in the dentate gyrus of hippocampal slices prepared from 6-8-day-old rat pup. Baclofen (0.25-1.0 microM), a GABAB agonist, rapidly and potently disinhibited the developing dentate, similar to its…
