The roles of the lateral intraparietal area and frontal eye field in guiding eye movements in free viewing search behavior
Koorosh Mirpour, James W. Bisley · Journal of Neurophysiology · 2021
The lateral intrapareital area (LIP) and frontal eye field (FEF) are known to contribute to guiding eye movements, but little is known about the unique roles that each area plays. Using a free viewing visual search task, we found that LIP provides a stable map of the visual world, integrating task rules and stimulus identity. FEF activity is consistently modulated by more complex information but, just before the saccade, integrates all the information to make the final decision about where to move.
