FIELD: medicine.SUBSTANCE: group of inventions relates to medicine. Device for induction of controlled hypothermia of the subjects brain contains two cryoapplicators, a coolant cooling device, a hydraulic system, means for registering the temperature of at least one body portion of the subject and the control means. One cryoapplicator is made in the form of a cryo-applicator-helmet, the inner surface of which is in contact with the surface of the skin of the scalp of the subjects head. Another cryoapplicator is designed as a cryoapplicator-collar, the inner surface of which is in contact with the subjects neck in the area of the projection of the internal carotid arteries. Both cryo-applicators are designed to circulate in them a liquid coolant. Hydraulic system is arranged to circulate a liquid coolant in at least one of said cryoapplicators. Temperature recording means includes at least one antenna for non-invasive recording of the intrinsic EMV of the subjects deep tissues in the microwave range and the subsequent determination of the brain temperature of the subject. Control means is configured to control the cooling means of the coolant and the hydraulic system, as well as to determine the need for cooling cryoapplicators and the adequacy of hypothermia of the brain of the subject, depending on the data obtained with the help of these temperature recording facilities. Mmethod for inducing controlled hypothermia of the subjects brain includes: fixing the first cryoapplicator (cryo-applicator-collar) on the subjects neck, which requires lowering the temperature of the brain, and carrying out the cooling procedure through the first cryoapplicator for 15–120 minutes measuring the rate of cooling of the subjects brain by means of an antenna for non-invasive recording of the EMR of the deep tissues of the subject in the microwave range when determining the insufficient speed of cooling the brain of the subject, fixation of the second cryoapplicator (cryo-applicator-h
