Homeostasis and dyshomeostasis in language and violent acting out. A dialogue between neuroscience and psychoanalysis.

In this article we consider the question of homeostasis and memory from the perspectives of neuroscience and psychoanalysis. Our aim is to describe a link between homeostasis/dyshomeostasis, memory/language, and violent acting out. Our study is based on clinical observations concerning two groups of persons: those who were incarcerated for perpetrating non-premeditated murder and those who were victimized by violent trauma in their lives. The clinical findings, combined with the analysis of the relevant literature and research, demonstrate that the dyshomeostatic state, through a positive homeostasis, can drive the person to restore the balance by their usual coping mechanisms and thereby generate negative homeostasis. These acts-all violent, non-premeditated, and forms of desubjectivized acting out-stem from being outside language on account of two pathological extremes of memory, its absence or its excess. Aided by neuroscience and the results of our clinical findings, we support the practice of recalling and strengthening memory traces of trauma in psychotherapy.
