Trial-by-trial behavior can be predicted from 8Av/45 activity. We trained support vector machines to separate correct trials with button presses (hit trials) from trials without button presses (correct rejections) based on time-locked LFPs recorded from 8Av/45 during test stimulus presentations. When the monkeys’ behavior was based only on stimulus color or a conjunction of color and motion (conjunction task), this decoding became significant between 148–164 ms after test stimulus onset for both monkeys. For decisions based only on stimulus motion, we observed lower decoding performances and later onsets (216–220 ms). Orange, right-hand axes correspond to cumulative reaction-time distributions for each trial group and their corresponding target trials. Dashed, orange lines at 300 ms indicate the start of response windows. No button presses occurred before this time. Other analysis details and plot layout like in Fig. 3.
