Choline acetyltransferase (ChAT) and acetylcholinesterase (AChE) activities were assayed in samples dissected from sagittal sections through rat superior colliculus. The magnitude of ChAT activity was about half to equal that found in rat whole brain in all layers except stratum griseum intermediale, where the average activity was higher than whole brain. AChE activity was three to four times that found in rat whole brain in superficial layers and about the same as average brain in deeper layers, except in the statum griseum intermediale, where the average activity was about twice whole brain. Rostral-caudal gradients in both ChAT and AChE activities occurred in stratum griseum intermediale, with activities in the caudal region of some animals as high as four times those in the rostral. ChAT activity in samples associated with locations of patches or spots of AChE staining product in stratum griseum intermediale was significantly higher than in samples from "nonpatch" regions. Results are discussed relative to inputs into the colliculus, whose terminations may correlate in location with the distributions of the enzyme activities.
