Target-locational dependence of task-related neural activity for the entire population of neurons. A: firing rates (solid lines) ± SE (shaded regions) during each analysis epoch normalized by the firing rate during baseline (unit circle, black) to each of the 8 target locations. B: the distribution of preferred target locations among neurons with significant mutual information. Bar lines for the different analysis epochs are colored as in A. C: distribution of differences in preferred target locations for pairs of analysis epochs among neurons with significant mutual information in both analysis epochs. In B and C, the angles of some bars are offset to aid visualization; true angles for all epochs (B) and epoch-pairs (C) are the same as the central bar.
