An investigation was made of the conditioned reflex activity in the adult offspring of dogs who had sustained chronic intravenous beta -irradiation, as a result of daily administration of Sr/sup 90/ with food (0.2 to 0 02 mc/kg) for a period of 17 to 28 months. This action, as assessed by the changes of defense conditioned reflexes, leads to a biological inferiority of the offspring as indicated by a decrease of the force and mobility of nervous processes and disturbance of their reciprocal steadiness. The progeny of chronically irradiated dogs have a very pronounced affinity for the inhibitory process. A relatlvely rapid evolvement of defense conditioned reflexes, difficulty of their extinction, a reduced capacity for precise differentiation, and a susceptibility to nervous activity disruption are common characteristics. The disorders of the reactivity of the great hemispheres of the brain are one of the earliest indices of remote sequelae of irradiation. (tr-auth)
