Fig. 1. Topographical analyses of the frequency of sensations. The hand is shownpalm up. The colored scale of the reduced-size flanker hands represents the percentage of participantswho
reported sensations. The central hand is an exact probabilitymap based on the difference between good and poor heartbeat perceivers. Only clusters significant at p b 0.001 are presented.
Reddish cells denote the supremacy of good heartbeat perceivers, bluish cells the supremacy of poor heartbeat perceivers. Color shading on the probability map represents different
probabilities.
