Intense light deprivation as a factor in stress disorders of behavioral reactions and cognitive functions in the experiment

Objective: to study the efect of light desynchronosis on behavioral reactions and cognitive functions of white male rats. Material and Methods. The study was conducted on 36 intact non-pedigree white male rats, which were divided into 2 groups: experimental and control.
