abstract="Recently, the gamma band (?; 70-100 Hz) has been implicated in sustained attention decay across a vigil consistent with computational models of fatigue. Frontal ? indexing centrally controlled sustained attention and parietal ? linked to gated sensory processes declined across a 10-minute vigilance task, a pattern observed for faster but not slower performers. The anatomical distribution of ? activity indicates neural communication, or connectivity, within the fronto-parietal network. We used Granger Prediction to evaluate fatigue effects on network ? connectivity. <br><br>RESULTS showed stronger directional connectivity for frontal?parietal versus parietal?frontal over time, indicating that top-down control of attention largely remained intact. However, parietal?frontal early ? connectivity increased with time, suggesting a network shift to enhanced sensory-directed processes after only 8 minutes. This pattern of connectivity was mirrored by fast but not slower performers. Our findings provide new directions for computational accounts of fatigue mechanisms and highlight the importance of individual differences.<p /> <p>Language: en</p>",
