a trend toward significanceP = 0.07
However, when comparing baseline to tremor episodes, there was a significant increase in heart rate ( F (2, 44) = 3.6, P = 0.037; t (22) = 2.6, P = 0.01) and a trend toward significance for an increase in pupil diameter ( F (2, 28) = 2.9, P = 0.07; t (14) = 2.1, P = 0.05), whereas this effect was not present for cerebral integration.
