Physiological responses of participants with PTSD during mental imagery of personal traumatic events. Light grey bars (left) placebo (n = 10) and medium grey bars (centre) propranolol-I (n = 9) are from samples from Brunet et al.1 Black bars (right) propranolol-II (n = 22) are from our study. Error bars represent standard error of the mean. Dashed lines represent empirical cut-offs for PTSD based on prior research.

MANOVA: F = 2.25, df = 6/70, P < 0.05. BPM = beats per minute; μS = μSiemens; μV = μVolts
