THE FIRST PREMISE OF THE MODEL HOLDS THAT THERE ARE INNATELY ORGANIZED NEURAL SYSTEMS IN THE BRAINS OF ANIMALS AND HUMANS WHICH, WHEN ACTIVE IN THE PRESENCE OF PARTICULAR STIMULI, RESULT IN DESTRUCTIVE BEHAVIOR TOWARD THOSE STIMULI. THE AGGRESSION SYSTEMS OF THE BRAIN ARE NOT ACTIVE MOST OF THE TIME, BUT CAN BE EVOKED BY FRUSTRATION. IT FOLLOWS THEN, THAT AGGRESSIVE BEHAVIOR COULD BE REDUCED BY CHANGING THE ENVIRONMENT OF THE INDIVIDUAL TO CONTAIN LESS FRUSTRATION AND DEPRIVATION AND POSITIVE REINFORCEMENT OF NONAGGRESSIVE RESPONSES OR THE NEGATIVE REINFORCEMENT OF EXPRESSED AGGRESSION. THERE IS ABUNDANT EVIDENCE THAT MAN HAS INNATE NEURAL AND ENDOCRINAL ORGANIZATIONS WHICH, WHEN ACTIVATED, RESULT IN HOSTILE THOUGHTS AND BEHAVIORS. HOWEVER, STUDIES SUGGEST THAT CONTROL IS POSSIBLE THROUGH BRAIN LESIONS, BRAIN STIMULATION, OR MANIPULATION OF THE INTERNAL ENVIRONMENT WITH HORMONES OR DRUGS, SUCH AS ESTROGENIC SUBSTANCES, TRANQUILIZERS, AMPHETAMINES, AND BENZODIASEPINES.
