What the Brain Requires
Goldberg's catalogue of the non-negotiable biological conditions for prefrontal function — sleep, exercise, waking recovery, and social engagement — whose violation produces the functional signatures of executive impairment regardless of tissue integrity.
The requirements are mundane. The simplicity is deceptive. Each item is obvious and systematically violated by the conditions the AI-augmented workflow creates. The brain requires sleep — not as wellness recommendation but as neurological necessity for memory consolidation and synaptic pruning. It requires physical exercise — the cardiovascular fitness that maintains cerebrovascular health in the most metabolically demanding cortical region. It requires waking recovery — the low-demand cognitive periods that allow prefrontal circuits to reset between coordination sessions. It requires social engagement — the specific cognitive work of interacting with autonomous minds that exercises the social-cognitive circuits the prefrontal cortex evolved to handle. Remove any one chronically and the executive degrades, regardless of how intact the neural tissue remains.

Sleep performs two operations that cannot occur during waking: memory consolidation (transfer of templates from hippocampal buffer to cortical storage) and synaptic pruning (elimination of weak connections to maintain signal-to-noise
