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
聯想性編碼是通過學習由一些具有特殊功能的神經元建立的，這些神經元具有將時間性關聯刺激的表徵聯系起來的能力。其次，不僅來自視網膜的底-頂信號，而且來自前額葉的頂底信號都能觸發聯想性編碼的提取，既可以作為有意識回憶的神經基礎，又是頂-底加工影響視覺過程的基礎。腦損傷病人研究具有高時間解析度的人類功能性核磁共振成像functional magnetic resonance imaging ， fmri和猴fmri研究以及猴細胞電生理分析相結合，將進一步加強人們對視覺腦機制的全面理解。
