Cortical circuits in the frontal eye fields and parietal cortex generate a 3-6 Hz rhythm that samples behaviorally relevant information in narrow, repeating windows. Working memory readout depends on which phase of the theta cycle aligns with target content. The 2 PM wall is not fatigue — it is theta desynchronization, and the mechanism is precise.</p>
