  • Title: Neural activity in the frontal pursuit area does not underlie pursuit target selection.
    Author: Mahaffy S, Krauzlis RJ.
    Journal: Vision Res; 2011 Apr 22; 51(8):853-66. PubMed ID: 20970442.
    Abstract:
    The frontal pursuit area (FPA) contains neurons that are directionally selective for pursuit eye-movements. We found that FPA neurons discriminate target from distracter too late to account for pursuit directional selection. Rather, the timing of neuronal discrimination is linked to pursuit onset, suggesting a role in motor execution. We also found buildup of activity of FPA neurons prior to pursuit onset that correlated with eye acceleration. These results show that the FPA is unlikely to be involved in selection of initial pursuit direction, but could be involved in motor preparation by increasing pursuit gain prior to pursuit onset.
