[Advantages of ultrasonic surgical instruments in experimental neurophysiology].
The effect of ultrasonic neurosurgical instruments on the functional state of the brain and its individual structures was studied to establish the most adequate and the least traumatic method of brain structures extirpation. Cortical zones were destroyed by ultrasound, thermocoagulated or extirpated. Parallel recordings of evoked potentials to single and paired stimuli were performed in adjacent neocortical areas. It was established that ultrasonic instruments permit the least traumatic extirpation of brain cortical zones.
