The results suggest that visual experience has a facilitating effect on morphological differentiation of bipolar cells , and early mature bipolar cells could provide light dependent signals to guide synaptic connections of ganglion cells in the inner retina 本篇结果证明了视觉经验可促进双极细胞的形态发育，并可进而推论早期成熟的双极细胞提供了光传入视网膜的讯号，再进一步去影响内层视网膜中神经节细胞在发育过程中的突触连结。
Multifocal visual electrophysiology examining system is designed by erich . e . sutter recently , which records retinal bioelectric response to light stimulus . he stimulated different retinal regions by graphics and , at the same time , recorded mixed signals of response by a common electrode 他利用图形刺激器分别刺激视网膜的多个不同部位，用一个通道的常规电极纪录多个不同部位的混合反应信号，再经计算机程序处理，把对应于各部位的波形提取出来，并用一立
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。
