Increase in spiking during whisker movement is predominantly observed in L5A. (A and B) Correlation of spiking frequency during quiet and whisking episodes with respect to recording depth (see also Fig. 2C). In A and B, only units are shown that were characterized by either a significant decrease or significant increase in spiking during whisking, respectively. Note that a significant decrease in spiking was observed throughout the different layers of the cortical column but that a significant increase was observed almost exclusively for neurons recorded in L5A.
