Whisker deafferentation and the bilateral coordination of whisking. A, Effects of bilateral deafferentation. Frequency distributions of time differences between amplitude peaks in the right and left C-1 whiskers before (top) and after (bottom) bilateral infraorbital sectioning performed in a single stage. The data shown in the graph represent group means for the three animals.B, Cross-correlograms of whisking movements on the right and left sides of the animal before (top) and after (bottom) unilateral infraorbital nerve sectioning. Peak shifts in the second and third components reflect the increased whisking frequency. Data are for a single representative animal.
