A variety of drugs which were thought to selectively effect the synthesis, release or reuptake of the biogenic monoamines, and thereby deplete their stores in brain, were administered to rats. The animals were given intraperitoneal injections of reserpine, α-methyl-meta-tyrosine, α-methyl-para-tyrosine, para-cholorophenylalanine and tetrabenazine, and were killed at intervals known to cause maximum depletion of serotonin, dopamine and norepinephrine. When compared to saline controls, the drugs depleted the respective monoamines, as expected, but changes in the levels of acetylcholine, alanine, glycine, γ-aminobutyric acid, and aspartate and glutamate were also observed.
