In order to study the biological factors of violence, it is presented the neurobiological research of agression in man and animals. We discuss the controversial aspects of the ethology and the social anthropology. Al the end, the interpretation of social violence should be done taking on account the psychobiological factors. Unfortunately the research about violence in Peru, it did not look for the biological aspects of this problem.

Con el objetivo investigar los factores biológicos en el desarrollo de la violencia, se presentan los estudios neurobiológicos de la agresión y la violencia en animales y en hombres. Se discute los aspectos controvertidos de la etología y la antropología social, se trata de interpretar la violencia social sobre la base de los factores psicobiológicos que aparentemente han sido relegados en los trabajos acerca de la violencia desarrollados en nuestro medio.

Up to date anatomical and biochemistry studies related to Brain mechanisms of behavior are reviewed. This type of research shold be work up in clinical psychology related to prevention, diagnostic and therapy of behavior disorders. In this way, the clinical psychology should make clinical research at differents age groups of the population. He will be able to study epidemiological risk factors together with neuropsychologycal tests and Brain imagind studies.

Through an attractive hypothesis of work, we present the relaTionship between the frontal lobes and the neurobiological bases of Freud's psychoanalytic theory. We review and discuss the psycophysiological and clinical aproachs, in order to understand this relationship, arriving to the final examination of the organic and functional "disolutions" of the brain. We study and discuss the clinical progressive symptoms of the dementia and the differencial diagnosis of abnormal behavior, inrerpreted under the bases of Freud's theory. In this way it would be possible to arrive through some tempting interpretation of the psychopatic behavior, drug addiction and the last "syndrome of terrorism".
