背景：非标准视角下物体识别的神经相关性尚不确定，但有证据表明参与神经通路，可能与标准视角下物体识别所用的神经通路不同。方法：8名正常受试者被要求识别非标准和标准方向物体的数字照片时，使用Boxcar功能MRI（fMRI）技术检测神经活动。结果：右侧角回、左侧颞下回和右侧小脑在非标准视角下表现出显著的fMRI活动。主体在非规范方向上识别物体的过程与在规范方向上识别物体的过程是分开的，或者是附加的。
Background:The neural correlate of object recognition in non-canonical views is uncertain, but there is evidence for involvement of neural pathways, possibly separate from those used for object recognition in canonical views.Methods:Boxcar functional MRI (fMRI) techniques were used to detect neural activity while eight normal subjects were instructed to identify digital photographs of objects in non-canonical and canonical orientations.Results:The right angular gyrus, the left inferior temporal gyrus, and the right cerebellum showed significant fMRI activity during non-canonical as opposed to canonical viewing.Conclusions:Subjects recognizing objects in non-canonical orientations engage in a process separate from, or in addition to, the process used in recognizing objects in canonical orientations.
