title: Lysergic acid diethylamide: sensitive neuronal units in the midbrain raphe.
abstract: Units in areas of the midbrain rich in neurons containing serotonin respond to parenteral injections of d-lysergic acid diethylamide by a reversible cessation of spontaneous activity. The dose required is at or below threshold for gross behavioral effects. An inhibition of neurons containing serotonin after administration of d-lysergic acid diethylamide could account for the decreased metabolism of serotonin produced by this drug.
