A neural correlate for common trait dissociation: Decreased EEG connectivity is related to dissociative absorption.

Dissociative absorption—a tendency to become deeply immersed in an experience while losing awareness of one's surroundings—is linked to reduced electrical connectivity in the brain. In 84 healthy Israeli soldiers, resting-state EEG showed that those with higher dissociative absorption had decreased coherence (a measure of connectivity) between frontal and occipital regions, and between central and parietal regions. These effects were strongest in the left hemisphere and in slow-wave brain rhythms (theta and delta). The findings suggest that dissociative absorption reflects less integrated cortical activity, offering insight into the neural basis of consciousness and personality.
