Effect of attention on the firing rate during the 200 ms period of maximum gain change. (A) Monkey M1. Spikes are counted between t = 1.8 and 2.0 seconds. (B) Monkey M2. Spikes are counted between t = 0.8 and 1.0 seconds. Data in both panels are from neurons that increased their firing significantly during the peak firing epoch ( p < 0.05, t-test). Best-fitting slopes, with 95% confidence intervals, were 1.85 ± 0.23 (M1) and 1.70 ± 0.11 (M2). The corresponding y-intercepts were 3.77 ± 4.26 (M1) and 0.85 ± 2.18 (M2).
