Figure 7. The left and right whisking oscillators are independent from one another.

Figure 7

(A) Bilateral kainic acid injection produces independent vibrissa movements on the left and right sides of the face. (B) Spectral coherence (black trace) between the movements of each of the vibrissae in (A). The two signals show low coherence in the band of whisking frequencies relative to control data for bilateral active whisking in alert animals (gray trace). (C) Representative traces of whisking and respiration used to compute average bilateral coherence between sniff-related and intervening whisks in three head-restrained rats. (D) Average coherence between left and right intervening whisks is lower than that of sniff-related whisks. Light blue and red areas represent 95% confidence interval. (E) Whisks on the left and right sides of the face display virtually no phase difference during sniff-related whisks (red line), whereas intervening whisks display a clear phase shift (blue line).
