Normally reared group housed mice do not show this enhanced violence under the influence of amphetamine. By analogy one cannot form a perception of p. Additional brain-behavioral studies involving platelet serotonin in isolation reared violent monkeys was initiated by the Developmental Behavioral Biology Program, NICHD and those findings were reported by Coleman Positive findings of impaired brain function in violent offenders would lead to specific therapeutic programs to correct this impaired brain function while serving as a criteria to maintain such individuals in custody for the protection of society. The implications of the Mason and Berkson "swinging mother surrogate" study for human development is profound but, unfortunately, remains unappreciated despite the fact that its dramatic effects can be seen in the Time Life documentary film "Rock a Bye Baby" Dokecki and which has been one of the most successful documentaries of Time Life. Violent isolation reared monkeys had significantly lower platelet serotonin levels than normally reared monkeys. The absence of any one of these three emotional senses in the development of the infant, e. Pleasure that is experienced only at the genital-spinal reflex level or limbic level of brain function does not result in the inhibition of sexually exploitative and violent behaviors. If these research programs had been permitted to continue and were proven to be successful, we can only speculate on how many lives could have been saved, particularly of children and women, by identifying such dangerous violent offenders and keeping them in custody until treatment was proven to be successful. These and related behavioral studies involving the effects of sensory deprivation and the social isolation rearing of infrahuman primates by psychologists Austin Riesen at Yerkes Primate Center in Atlanta, Georgia and of the Harlows at the University of Wisconsin provided a theoretical and experimental frame of reference for the brain studies which I initiated on isolation reared maternal-socially deprived monkeys at the National Institute of Child Health and Human Development NICHD , National Institutes of Health NIH. More on this story later. All three emotional sensory systems, of course, are involved in the experiencing of "Pleasure" and "Bonding". I believe that a safe and non-invasive neuropsychological diagnostic test of impaired brain function could be developed to identify the "dangerous" violent offender which would translate into the savings of human life lost to such violent offenders who are prematurely released from protective custody and back into the community to commit more violent crimes. It is at these lower levels of brain processing of sexual pleasure where sado-masochism flourishes Prescott, ; Canada where I was made acutely aware of the extraordinary importance that the early sensory-social environment p. The failure to encode the infant's developing brain with the smell of its mother's body through breastfeeding can only have long-term adverse consequences for bonding and for the male-female sexual relationship. Abnormal brain electrical activity and abnormal neuroanatomy of brain cells abnormal dendrites and dendritic spines were found in somatosensory and motor cerebral neocortex and in cerebellar cortex.
