Rats ranging in postnatal age from 6 hours to 28 days were implanted with cortical and depth electrodes as well as an indwelling cannula in the lateral ventricle. We then administered varying amounts of the opiate peptides leucine-enkephalin and beta-endorphin intracerebroventricularly with continuous electroencephalographic monitoring. Leucine-enkephalin(More)
We have devised a method of stereotaxic implantation of electrodes in cortical and subcortical sites in neonatal and infant rats and subsequently recording from these animals as they move about freely. We studied the development of the EEG recorded from these cortical and subcortical sites in animals ranging in age from 1 to 84 days and analyzed the EEGs(More)
