Right but not left angular gyrus modulates the metric component of the mental body representation: a tDCS study.

abstract：:Encoding of visual target location in extrapersonal space requires convergence of at least three types of information: retinal signals, information about orbital eye positions, and the position of the head on the body. Since the position of gaze is the sum of the head position and the eye position, inaccuracy of spati...
