WebJul 1, 1990 · The phencyclidine (PCP) derivative N-(1-(2-thienyl)cyclohexyl)-piperidine (3H-TCP) was used to label in vivo the N-methyl-D-aspartate (NMDA) receptor-associated ionic channel in the mouse brain. After the injection of a tracer dose of 3H-TCP, a spread labeling throughout the brain was observed, but was the highest in the cerebellum.
