This article presents an interpretation of the neuroscience?s theories that relate neurophysiologic functions and brain damages
to the violent behavior in order to present some ethical points about the use of these hypotheses in some fields of work such
as criminal justice, education an public health. Even some neuroscientists admit that there isn't enough evidence that criminal
behavior could be linked to discrete brain functions, questioning the controversial use of neuroimages as proof of irresponsibility
in criminal judgments.
There is a present tendency to map the violent brains of children and teenagers in order to intervene as early as possible
to prevent violence. Such a perspective seems to pose a false problem. Maybe this is not a na?ve option, because there are many
investments and capitalistic interests behind such approach. That's why this article analyzes with caution the large amount of
investments in brain scan polices. In addition, the studies of violent emotions in a specific locus of the brain recalls the core
of historical mistakes made in the XIX century by Phrenology and Criminal Anthropology that saw the sign of crime in the
physiognomy of some social and ethnic types. It is equally important to warn about the risk of reducing the multiplicity of human
emotions and violent reactions to neural causes, supposedly determining criminal potential. Or, there is no crime without a
context, and the weight given to social issues should be much clarified. Supported by psychoanalytical and educational premises,
this work criticizes the reductionism of a certain criminal neuroscience, and focuses on the irreducibility of linguistic, social and
historical contributions as the main factors in the formation and transformation of subjectivity and its misfortune in crime.
