Extended Data Fig. 1: Normalized spatial distance between different functional classes of neurons within lateral prefrontal cortex.

Seven functional classes of neurons were defined according to selective activity to three task components: visual, delay, and motor. Neurons were defined as having a given functional property based on the presence of significant selectivity across cue conditions within the visual, delay and motor epochs of the task. The plot shows the mean distance between different classes of neurons; means were calculated and normalized by each session’s total mean distance. Top-left to bottom-right diagonal elements show the mean distance within each functional class. Interestingly, we did not observe a relationship between depth and different functional subclasses (not shown), although this result should be interpreted with caution due to our non-perpendicular electrode penetrations.
