Figure 2.
(A–C) Responses of three exemplary OMV PC SS units to saccades of different amplitudes and to SPEM in the same direction (A. 180° (left), B. 135° (upper-left), C. 0° (right)). The neuronal activity is characterized by raster plots (4 upper rows) and by mean spike density functions (last row) aligned to movement onset are plotted below the raster plot. 10°, 7°, 4° saccades and SPEM are represented in green, blue, red and black respectively. The partially transparent bands surrounding the mean spike density functions reflect the SEM. (D) Histogram of preferred saccades amplitudes based on n = 133 units. (E) Plots of population activity of all bursting units (n = 69, closed lines) and all pausing units (n = 64, dash line) for 10° (green), 7° (blue) and 4° (red) saccades. Population activity for SPEM is plotted in black.
