PDC during different behavioral states. During the whisker twitching state there was a significantly larger amount of directed coherence from SI to VPM than from VPM to SI (∗). In addition, the amount of directed coherence between SI and VPM during whisker twitching was larger than during any other behavioral state. Black bars show directed coherence from VPM to SI, and gray bars show directed coherence from SI to VPM. Values were normalized to the amount of classical coherence for each measure.
