Abstract
The chaotic component of the high-frequency EEG of the rabbit was stud ied during repeated presentation of non-rhythmical light stimuli. The chaotic component was found to be sensitive to the action of these sti muli, its reactions being variant in different cortical areas. Dimensi on changes were revealed corresponding to a manifestation of the phasi c and tonic components of the orienting reaction. In the course of ori enting reflex extinction the chaotic component characteristics changed in correspondence with the activation level shifts in the cortical ar eas under study.
