THE NEUROBIOLOGY OF DISSOCIATIVE DISORDERS(The mind – body – brain disunity and consciousness)

Avinash De Sousa*

Abstract

This article reviews studies on the neural correlates of dissociative processes and their contributions to the understanding of consciousness. Various studies using latest neuro-imaging modalities like positron emission tomography, magnetic resonance imaging and functional magnetic imaging resonance are synthesized along with key cortical structures like the medial prefrontal cortex, anterior cingulate cortex, somatosensory cortex and insula. The role of the thalamus and cerebellum in dissociation and consciousness are examined. Distinctive neural correlates of primary and secondary dissociative experiences are examined in the light of psychiatric problems like post traumatic stress disorder. Disconnection of various neural pathways linking self awareness with body state perception occurring as a result of childhood trauma and its implications on dissociative states and consciousness are examined. We also examine a self that is divided, multiplied or perforated by trauma and a self that dissociates turning attention away from external threat and trauma. 

Key Words: Dissociative Disorders; Consciousness; Post traumatic stress disorder
