[Reference system for representation of the subjective "straight ahead" position].
Representation of space by the neural system is supposed to be carried out by neural networks which describe space in different reference frames fixed relative to body segments or external objects. This study focuses on finding a reference frame for representation of the subjective "straight ahead" position. An experiment is described where deflections of the subjectively defined "straight ahead" position from the objective position in front of the trunk are measured when the subject's head is deviated to the right or to the left. Individual preferences for either the head-fixed reference frame or the trunk-fixed frame are revealed. It was shown that there are differences in subjective representation of the "straight ahead" position depending on the left or right turn of the head, which is supposed to be connected with brain asymmetry in spatial perception.
