Summary of FEF and SC inactivation effects on attention and saccades. a Summary of 46 muscimol inactivations of the SC, showing detection rates before (green) and during (blue) inactivation, when motion-direction changes occurred inside (filled) or outside (open) the affected portion of the visual field. Sessions are rank-ordered based on the size of the change in detection rate asymmetry caused by inactivation. b Summary of 23 muscimol inactivations of the FEF, using same conventions as in a. c Summary of 30 sham control experiments. d Changes in detection rate asymmetries caused by SC inactivation. Positive values indicate that, during inactivation, the difference in detection rates between the two patches became more asymmetric in favor of changes outside the affected region. e Changes in detection rate asymmetries caused by FEF inactivation. f Changes in detection rate asymmetries during sham controls. g Asymmetry in the latencies of saccades during SC inactivation observed with the visually guided saccade task. Positive values indicate that saccades made to locations on the affected side had longer latencies than saccades made toward the unaffected side. Only locations falling within the boundary of the two patches in the attention task were considered. Sessions are rank-ordered based on the data in d. h Asymmetry in the latencies of saccades during FEF inactivation. Sessions rank-ordered based on the data in e. i Asymmetry in the latencies of saccades during sham controls. Sessions rank-ordered based on the data in f.
