The immediacy and directness of our visual experience belies the complexity of the underlying neural mechanisms, which remain incompletely understood. Recent neuroimaging studies suggest that activity in ventral visual cortex is necessary but not sufficient for visual awareness. Experiments in both patients and normal subjects indicate that parietal and frontal areas make an important contribution to visual awareness, suggesting that reciprocal interactions between dorsal frontoparietal areas and ventral visual cortex may provide a fundamental neural substrate for conscious visual experience.
我们视觉体验的即时性和直接性掩盖了其背后神经机制的复杂性，而这些神经机制仍未被完全理解。最近的神经影像学研究表明，腹侧视觉皮层的活动对于视觉意识是必要的，但并不充分。对患者和正常受试者的实验均表明，顶叶和额叶区域对视觉意识有重要贡献，这表明背侧额顶叶区域与腹侧视觉皮层之间的相互作用可能为有意识的视觉体验提供了基本的神经基础。
