Cell-class response properties during EXE and OBS

(A) Average net firing rates of facilitated neurons of cell class 1 (red), 2 (blue), and 3 (green) during object presentation (0.1 to 0.3 s relative to object presentations) and movement epoch (0.3 s before to 0.9 s after the Go-signal) in EXE (left) and OBS (right) tasks (one-way ANOVA with Newman-Keuls post hoc test). Cell class response is shown in Figures S4A and S4B.

(B) Average peak of net firing rates of facilitated neurons of the three cell classes during object presentation (0.1 to 0.3 relative to object presentations) and movement epoch (0.3 s before to 0.9 s after the Go-signal) in EXE (left) and OBS (right). Conventions as in (A). ^∗p < 0.05; ^∗∗p < 0.01; ^∗∗∗p < 0.001. Cell class response is shown in Figures S4A and S4B.

(C) Mutual information on Go/No-Go trials (top) and type of object (bottom) during EXE decoded from neuronal population activity of each area during the task-unfolding period. Mutual information about object during EXE conveyed by neurons of Class 3 is greater than that of neurons of Class 1 (z test, p = 0.046) and 2 (p = 0.090). Conventions as in Figure 2C.

(D) Mutual information about Go/No-Go (top) and type of object (bottom) during OBS. Conventions as in Figure 2C.
