Feature-based attention effects during the first fixation when the subsequent saccade was directed to stimuli in the RF. Normalized population average firing rates in (A) FEF and (B) LIP. (C) Decoding accuracy for target vs. no share conditions across the FEF and LIP populations shown in a time-resolved manner. Classification is based on 20 trials from each condition. Chance is at 50%. The blue horizontal line at the top of the graph indicates periods that classification accuracy was significantly higher for FEF compared with LIP (P < 0.001, permutation test). Other conventions are as in Figs. 2 and 3.
