Movement Encoding: Bar graphs show the percentage of units that showed an increase or decrease in firing rate with respect to layer. (a) Aggregate analysis shows no statistically significant difference (p=0.69) in the total number of units that modulated activity between the upper (n=313) and lower layers (n=320). Upon consideration of the kind of modulation, units in the lower layers were significantly more likely (p=0.04) to increase than decrease their firing rate. We were unable to detect any such preference for the modulating units in the upper layers. (b) Best session analysis shows no statistically significant difference (p=0.06) in the modulation of unit firing rate between the upper (n=33) and lower layers (n=42) with respect to movement.
