Abstract
Chlorpromazine, promethazine, prothanon, butaperazine and a placebo were investigated for their effects upon the critical flicker fusion (CFF). The time course of the investigation differed from that in our first paper. No unambiguous effects of the phenothiazine derivatives on the CFF could be demonstrated. The investigation was therefore repeated with the method described in our first paper. The CFF now came down after phenothiazine much more than after placebo. The results of our experiments indicate their dependence on the time course of the examination of the CFF.
