生物运动识别的信息加工机制

Information Processing Mechanism of Biological Motion Recognition

识别其他生物体的运动对于个体的生存和社会交互都有极为重要的意义.本文首先基于生物运动识别的行为学、心理物理学、脑损伤和精神障碍研究介绍了生物运动识别的一些特性和影响因素;然后基于神经影像学、脑损伤和神经电生理学研究从视觉系统背腹侧双通路加工的角度,梳理了其信息加工机制的进展;最后对生物运动识别信息加工神经机制的研究方向提出了一点建议,并指出研究过程中需要注意的问题.

Recognizing the motion of biological entities is crucial for individual survival and social interaction in many species.The properties and influencing factors of biological motion recognition are summarized here,based on the studies in psychophysical experiments,lesions and mental disorder.Then,the main findings in neural mechanism of biological motion recognition are reviewed from the perspective of dorsal-ventral visual pathways,according to the experimental evidences in neuroimaging,lesions and neuro-electrophysiological studies.Finally,some matters and suggestions for future research about neural mechanism of biological motion recognition are put forward.
