研究发现，收缩的视觉刺激比扩张的刺激能诱发更强的视觉刺激。我们试图确定哪一种运动成分是收缩的优势基础，而不是扩张的优势。视流的右半视野或左半视野呈现给右眼或左眼。我们的结果表明，在没有颞鼻运动投射到鼻视网膜上的情况下，即使有收缩刺激，视觉也很弱。相反，如果存在这种类型的运动，即使有扩大的刺激，向量仍然很强。收缩刺激在诱发视觉方面的优势可能是由于鼻视网膜上加工运动的各向异性造成的。(C)2010爱思唯尔有限公司。保留所有权利。
Contracting visual stimuli have been found to induce stronger vection than expanding stimuli. We sought to determine which component of motion underlies the advantage of contraction over expansion in inducing vection. Either the right or left hemi-visual field of an optic flow was presented to either the right or left eye. Our results revealed that without temporonasal motion projected on the nasal retina, vection was weak even with contracting stimuli. Conversely, vection was strong even with expanding stimuli if this type of motion was present. The advantage of contracting stimuli in inducing vection may be caused by anisotropy in processing motion on the nasal retina. (C) 2010 Elsevier Ltd. All rights reserved.
