Significance tests for the effects of sensory stimulation (Brush, Cold, von Frey, Pin, and Heat) upon changes in Heart Rate and Mean Arterial Pressure for data shown in the top panels of Figures 2 through 6.

P values are shown for each main effect (underlined for P<0.05). The underlying F-statistic is shown in parentheses. A significant intercept term (equal to the grand mean squared, multiplied by the overall n) indicates an overall effect of stimulation on heart rate or mean arterial pressure. “df” row indicates between-group and within-group degrees of freedom for each analysis; “Group*Day” indicates the main effect of the interaction of Group and Day.
