Mescaline, 3,4-Dimethoxyphenylethylamine, and Adrenaline: Sites of Electroencephalographic Arousal

Abstract
Transections of the brain of rabbit reveal that electroencephalographic arousal produced by injections of adrenaline takes place at the midbrain level, while mescaline and 3,4-dimethoxyphenylethylamine induce such arousal lower in the brainstem, at the medullary level.
