Extended Data Fig. 1: Neural engagement showed stereotyped changes relative to experimental events, in multiple example sessions.

Same conventions as Fig. 2d. Note that in contrast to other figures (for example, Fig. 5c), here neural engagement is shown across trials to all eight instructed targets, where trials to different targets were interleaved. As a result, each time course shown here includes variability due to the target-specific differences in neural engagement during learning (for example, see Fig. 5c). Position along the horizontal axis indicates clock time (see legend indicating ‘5 minutes’), so that pauses in the experiment are more visible. All sessions are plotted with the same time scale, and trial indices are marked for reference.
