Multiplicative and additive components of attentional modulation observed in monkey M1 within two subpopulations. (A) Neurons that increased their firing rates during the first 600 ms of the stimulus. (B) Neurons from monkey M1 that significantly decreased their firing rates during the tactile (attended) task. Dotted lines indicate 95% confidence intervals computed using bootstrap.
