由于腹侧视觉通路的原始特征,我们的知识,其神经解剖,功能特性,和外在的目标已经大大增长。在这里,我们综合了最近的证据,并提出腹侧通路最好理解为一个经常性的枕颞神经网络的对象质量的神经表征,利用和约束至少有六个不同的皮层和皮层下系统。每一个系统都有其专门的行为、认知或情感功能,共同为腹侧视觉通路提供了存在的理由。这个扩展的框架与腹侧视觉通路的描述形成对比,腹侧视觉通路是一个主要由腹外侧前额叶皮层使用的连续分级结构,最终以单一物体表征为高潮,并且比这个帐户更简约,包括注意力,上下文和反馈效应。
Since the original characterization of the ventral visual pathway our knowledge of its neuroanatomy, functional properties, and extrinsic targets has grown considerably. Here we synthesize this recent evidence and propose that the ventral pathway is best understood as a recurrent occipitotemporal network containing neural representations of object quality both utilized and constrained by at least six distinct cortical and subcortical systems. Each system serves its own specialized behavioral, cognitive, or affective function, collectively providing the raison d’etre for the ventral visual pathway. This expanded framework contrasts with the depiction of the ventral visual pathway as a largely serial staged hierarchy that culminates in singular object representations for utilization mainly by ventrolateral prefrontal cortex and, more parsimoniously than this account, incorporates attentional, contextual, and feedback effects.
