OPN pause and trigger onset leads: cell averages. AA1 and AA2 compare average saccadic pause leads (x-axis) and average blink pause leads (y-axis) for the OPN cells acquired from animal A1 and animal A2, respectively. Trigeminal blink averages are identified by the black dots and spontaneous blink averages are identified by the gray × symbols. Symbols below the 1:1 dotted lines indicate pause onset for blinks occurring, on average, later than pause onset for saccades. BA1 and BA2 compare, with the same layout of the top panels, saccadic trigger leads and blink trigger leads, as defined in methods. The bars on the bottom right corners are the averages of the SDs of each cell subset for the 3 types of pause (trigger) lead measures. The shift in time for all cells of the trigeminal pause (trigger) lead values when compared with the saccadic pause (trigger) lead values is quite remarkable, clearly indicating that OPN pause onset has different functions for saccades and trigeminal blinks. The 2 animals present evident differences in their spontaneous blink lead values.
