Fig. 3 — Procedure for aligning data streams. This dataset contains three streams of raw data: neural recordings, video frames, and behavioral events. They are aligned by a synchronization pulse at the beginning of each trial, which is detected in all three streams at times Tr_N,i, Tr_V,i, and Tr_B,i for trial i. The same trial may be matched up across all streams, although the neural and video streams may be missing trials at the beginning or end of the session. To align the neural timebase (top) to the common video timebase (middle), we used a continuous alignment procedure. To align the behavioral timebase (bottom) to the common video timebase (middle), we used a trial-by-trial alignment procedure, which introduces slight discontinuities (no more than a few milliseconds) between trials.
