The displacement characteristics of [3H]5-hydroxytryptamine (5-HT1) binding by several serotonergic ligands were studied in the chick embryo brain. Although most of ligands tested displaced [3H]5-HT in a manner suggestive of a single site, displacement curves for (+/-)-8-hydroxy-dipropylaminotetralin (8-OH-DPAT), 5-methoxytryptamine, 5-methyltryptamine and(More)
Three monoamine oxidase (MAO) inhibitors--pargyline, clorgyline and deprenyl--as well as the serotonin (5-HT, 5-hydroxytryptamine) releasing agent fenfluramine were administered to developing chick embryos and the effects on [3H]5-HT binding parameters and endogenous 5-HT levels were assessed. Multiple, but not acute, pretreatments with any of the three MAO(More)
