A polygraphic study on resistance to habituation of the somatic, autonomic and EEG components of the orienting reaction elicited by a repetitive auditory stimulus was performed in 41 patients with epileptogenic cerebral tumors and in 128 matched subjects in 3 control groups. The study evidenced a significant higher resistance to habituation of the orienting reaction in patients with epileptogenic cerebral tumors than in control subjects. The degree of habituation disturbances depended on the seizure frequency and preoperative history, on the features of interictal EEG tracings and on the tumor surgical removal.
