视觉表征联想性编码顶-底信息加工颞下回皮层和前额叶皮层 - Bottom - up processing and feature detecting theory based on strong electrophysiological evidences has played a dominant role in the visual research for long time . people know top - down processing just by common sense . knowledge or experience are recalled from memory by reactivation of their neural representations and affected visual processes . however recently , researches from human and monkey provide experimental evidences for top - down processing . first , mnemonic representation of visual objects and faces , located in the ventral processing stream of visual perception in monkey , provide the best evidences of how neuronal codes are created by neurons that have the special ability to link the representations of temporally associated stimuli ; second , experiments suggest that not only bottom - up signals from the retina but also top - down signals from the prefrontal cortex can trigger the retrieval of associative codes , which may serve as a neural basis both for the conscious recall and for the visual processes affected by top - down processing further studies will improve people s understanding of the causal relation of activation and behavior by use of combined fmri and electrophysiology or lesion studies
联想性编码是通过学习由一些具有特殊功能的神经元建立的，这些神经元具有将时间性关联刺激的表征联系起来的能力。其次，不仅来自视网膜的底-顶信号，而且来自前额叶的顶底信号都能触发联想性编码的提取，既可以作为有意识回忆的神经基础，又是顶-底加工影响视觉过程的基础。脑损伤病人研究具有高时间分辨率的人类功能性核磁共振成像functional magnetic resonance imaging , fmri和猴fmri研究以及猴细胞电生理分析相结合,将进一步加强人们对视觉脑机制的全面理解。
