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.
神经系统对空间的表征被认为是由神经网络来完成的,这些神经网络在相对于身体节段或外部物体固定的不同参考系中描述空间。本研究着重于寻找一个用于表征主观“正前方”位置的参考系。文中描述了一项实验,当受试者的头部向右或向左偏斜时,测量主观定义的“正前方”位置相对于躯干前方客观位置的偏差。结果揭示了个体对头部固定参考系或躯干固定参考系的偏好。研究表明,“正前方”位置的主观表征会因头部向左或向右转而有所不同,这被认为与空间感知中的大脑不对称性有关。
