a, b. Population average of the normalized responses to motion stimulus in Attend and Ignore conditions before (a) and during (b) SC inactivation. Error bars indicate 68.2% CI. Grey window indicates time period used for computing attention-related modulation.
c. Distribution of attention-related modulation values across neurons before (median = 0.57) and during SC inactivation (median = 0.54). Solid and dotted lines indicate median and no modulation, respectively. Colored shading indicates significance for individual neurons (p < 0.05, bootstrap test).
d. Average attention-related modulation across simultaneously recorded neurons within a session (mean ± sd = 23.75 ± 8.72), before and during SC inactivation.
