Approaching the Neurobiological Scenario of Psychoanalysis

In this perspective review, it is adopted the neurobiological interactions and conflicts of both perceived realities and acquired memories with the instinctual drives to represent such terms and interactions as unconscious/preconscious/conscious or id/ego/super-ego of the Freudian theories in psychoanalysis. During waking, it is demonstrated the interactions and conflicts of realities/memories with the instinctual drives are present in all vertebrates including humans. For the rapid eye movement (REM) sleep, it is well evidenced to process the emotional memories, while disrupt the emotional balance toward depression, supporting the Freudian psychoanalysis. For the slow-wave sleep (SWS), it was demonstrated by Cai as ameliorating the depression caused by accumulated emotional memories, supplementing a new complementary half story neglected by Freudian psychoanalysis. It was simultaneously suggested the differentiation of the noradrenergic/serotonergic activities in waking and sleep result in the differentiation of conscious and subconscious interactions and conflicts in psychoanalysis. Finally, it is briefly depicted the gradual evolution of psychoanalytic interactions and conflicts in vertebrates, substantiating the scientific basis for these core contents of Freudian psychoanalysis. In all, due to the support and extension of the core Freudian theoretical contents as unconscious/preconscious/conscious psychoanalysis from neurobiology, it is approaching a prospective neurobiological scenario of psychoanalysis.
