visual electrophysiology 解釋
視覺電生理學
  • visual : adj. 1. 視覺的，觀看的；視力的。2. 看得見的。3. 光學的。4. 形象化的。adv. -ly （the visually impaired 〈委婉語〉盲人；視力很差的人）。
  • electrophysiology : n. 電生理學。
  • y :
  1. 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。
  2. Our multifocal visual electrophysiology examining system simulates veris system. we have analyzed functions provided by veris system and basic principles of the system. we have divided the system into several modules and then designed each part seperately

    本多焦視覺電生理檢查系統是在了解veris4 . 0多焦視覺電生理儀所實現的功能的基礎上，分析其基本工作原理，重新進行了系統設計。
  3. The multifocal visual electrophysiology examining system is strict with eye ' s fixation. so we design a monitoring system to monitor eye ' s fixation. finally, we have three methods to display the examining effects of multifocal visual electrophysiology examining system : traces, grouping traces, 3d - plot

    研製完成後，該儀器在重慶市第三人民醫院進行了近四個月的臨床試驗，確定了該儀器的正常值范圍，並對一些病人進行了檢查，與veris4 . 0系統的檢查結果進行對比，其結果基本一致。
  4. 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

    他利用圖形刺激器分別刺激視網膜的多個不同部位，用一個通道的常規電極紀錄多個不同部位的混合反應信號，再經計算機程序處理，把對應于各部位的波形提取出來，並用一立
  5. Because the signals exacted by the multi - focal visual electrophysiology examining system are very tiny. their amplitude is from 50 nv to 700 nv

    由於多焦視覺電生理信號相當微弱，從50nv - - 700nv不等，對信號的放大要求相當嚴格。
