[Visual perception, reaction time and their alteration under the influence of alcohol in patients with remote sequelae of closed cranio-cerebral trauma].
In patients with remote sequalae of closed brain injuries the author examined the time of perception of letter stimula by the aid of a technique of reverse masking, the time of motor reactions to simple and letter stimula and changes of these temporary parameters under the influence of small doses of alcohol (60 ml 40 degrees alcohol). The time of perception and time of motor reactions to a simple stimula were practically identical to those in normals. The time of motor reactions to aletter stimula was higher than to a simple one and in patients significantly higher than in normals. Under the influence of alcohol the time of perception and motor reactions increase in conditions of letter distinguishing. These facts permit to consider that alcohol in such patients makes the processing of information in the CNS slower and most strongly influences the central cortical processes.
