The influence with infrared lazer irradiation (wavelength — 0.89 mcm, power — 5.0 mVt, exposition — 10.0 min) upon the brain of male Waistar rats prevented the development of ictal epileptiform discharges and generalized seizures induced via i.p. benzilpenicillin sodium salt administration (300 000 IU/kg). The increase of duration of lazer irradiation exposition up to 30.0 min caused the increase of the length of ictal discharges.
