The default-mode, ego-functions and free-energy: a neurobiological account of Freudian ideas

Summary
Groundbreaking neuroscience suggests core Freudian concepts like the ego align with the brain's default mode network. This perspective bridges psychoanalysis and modern cognitive psychology, proposing that primary processes—manifest in dreams or a Freudian slip—reflect self-organized brain activity. Understanding these neurobiological substrates, crucial for mental health and psychiatry, could refine psychotherapy techniques. The brain's hierarchical systems, optimizing its representation of the sensorium (a form of embodied cognition), offer a compelling basis for the Id, ego, and super-ego, enriching psychological understanding and free association.
Abstract
This article explores the notion that Freudian constructs may have neurobiological substrates. Specifically, we propose that Freud's descriptions of the primary and secondary processes are consistent with self-organized activity in hierarchical cortical systems and that his descriptions of the ego are consistent with the functions of the default-mode and its reciprocal exchanges with subordinate brain systems. This neurobiological account rests on a view of the brain as a hierarchical inference or Helmholtz machine. In this view, large-scale intrinsic networks occupy supraordinate levels of hierarchical brain systems that try to optimize their representation of the sensorium. This optimization has been formulated as minimizing a free-energy; a process that is formally similar to the treatment of energy in Freudian formulations. We substantiate this synthesis by showing that Freud's descriptions of the primary process are consistent with the phenomenology and neurophysiology of rapid eye movement sleep, the early and acute psychotic state, the aura of temporal lobe epilepsy and hallucinogenic drug states.
