Autoradiographic studies on the distribution of 3H-2,3,4-trimethoxy-beta-phenylethylamine in the mouse.

The regional distribution of radioactivity was studied in the brain and in other organs of the mouse by light microscopic autoradiography after injection of 3H-2,3,4-trimethoxy-Β-phenylethylamine (2,3,4-TMPEA), a nonhallucinogenic isomer of mescaline. The distribution patterns were compared with biochemical and autoradiographic results obtained after 3H-mescaline.
