Figure 2. Correlated EMG activity of the examined jaw muscles. The scatter plots illustrate the relationships among the variables burst number, mean burst length, and duty time at the activity level exceeding 5% of the peak-EMG. Panels consist of data obtained during continuous EMG recording for 24 hrs, with each datapoint representing 1 hr. Data from all animals are presented in the same graph to facilitate comparison. r = Partial correlation of the variables displayed in the panel, adjusted for the remaining variable (averaged over all samples; number of samples is shown below muscle name).
