这篇文章探讨了弗洛伊德构念可能有神经生物学基础的概念。具体来说，我们提出弗洛伊德对初级和次级过程的描述与分层皮质系统中的自组织活动一致，他对自我的描述与默认模式的功能及其与下属大脑系统的相互交换一致。这种神经生物学的解释建立在把大脑看作是一个层次推理或亥姆霍兹机器的观点之上。在这种观点中，大规模的内在网络占据了等级大脑系统的上级，这些系统试图优化它们对感觉的表征。这种优化被表述为最小化自由能；这一过程在形式上类似于弗洛伊德公式中对能量的处理。我们通过表明弗洛伊德对初级过程的描述与快速眼动睡眠、早期和急性精神病状态、颞叶癫痫的先兆和致幻药物状态的现象学和神经生理学一致来证实这一综合。
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.
