FEF remapping dynamics in the full, recurrent model. Initiation of the motor command in the SC layer is labeled “Saccadic Command.” After an efferent delay of 70 ms, exaggerated to provide detailed analysis of the presaccadic period, the saccade occurred (time 0 on the abscissas). Each dot shows the state of activity in the FEF layer as it was updated in 10 ms intervals for neurons representing the Receptive Field (RF; orange), the Future Field (FF; blue), and a midpoint location between the RF and FF (white). Lines connecting the dots indicate the steady activity level at each FEF location until each update. The timing of the EP update is delayed relative to the Saccadic Command by (A) 0 ms, (B) 30 ms, and (C) 50 ms. Remapping was time-locked to the EP updates and jumped rather than spread, as there was no transient activity at the midpoint.
