A) The zebrin bands for all PCs were histologically identified. Some of the cells were somatically recorded; others dendritically. B) The zonal locations of an additional sample of PCs were physiologically determined. All cells were somatically recorded. A2 zone comprises mainly Z+ bands while the C1 zone comprises mainly Z− bands. Two cells recorded in Crus II A2 zone did not fire SSs and were not included in the analysis of SS firing rate.
