Control Limit Hypothesis: High Dopamine in Schizophrenia Is Compensation, Not Cause
burny_tech · x · 2026-11-10
A neuroscience thread presents the "control limit hypothesis": schizophrenia stems from glutamatergic miswiring that slows cortical attractor transitions, prompting the brain to raise dopamine as a compensatory mechanism to restore speed.
The key reframing: high dopamine is a response to underlying circuit dysfunction rather than the primary cause. This explains why antipsychotics alleviate psychosis without improving—and potentially worsening—cognitive performance, since they suppress the compensation rather than the root cause.
