Delta opioid receptors mediate seizures produced by intrahippocampal injection of ala-deltorphin in rats.


The effects of the selective delta opioid receptor agonist, ala-deltorphin, microinfused into the dorsal hippocampus or into the locus coeruleus, on the electrocorticographic (ECoG) activity continuously quantified in its spectrum were studied in rats. The microinjection into the dorsal hippocampus of ala-deltorphin (0.03, 0.3 and 1.0 nmol) produced dose… (More)
