  3. 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。

  7. It simulates the response characteristics of simple cells in biological visual cortex, and decomposes one image into sub - images with different resolutions and orientations in which every pixel represents the response of some neuron in the visual cortex

    該方法模擬生物視覺皮層中簡單細胞的響應特性，將單幅圖像映射成一系列分辨力及方向各異的子圖像，子圖像中每個像素代表了視覺皮層中某個神經元的響應。
  8. Through the study on the morphology of biological vision, its struct ure and mechanism of evolution and development are discussed ; emphasis are put o n the anatomic structure of visual way, hypothesis on the layer classification o f the reception field, parallel processing of the visual information, and the fe edback and conformity effect in visual cortex etc

    筆者通過對生物視覺形態學方面的深入研究，探討了生物視覺產生、發展的結構與機制，尤其研討了視覺通路的解剖結構、感受野分層級假設、視覺信息的并行處理性質及視覺皮層間的反饋和整合作用。
  9. Primary visual cortex

    初級視覺皮質
  10. Although researchers have failed to find evidence for a single “ time organ ” in the brain, in the manner of, say, the visual cortex, it may be that future work will pin down those brain processes responsible for our sense of temporal passage

    雖然研究人員至今尚未找到證據，來支持在大腦中存在一個時間器官的說法（所謂器官，是指如視覺皮質之類的東西） ，但或許未來的研究能夠找出這種使我們產生時間流動感的大腦過程。
  11. Those with pain lacked this visual feedback system, and showed no activity in the sensory or motor cortex

    感覺到疼痛的人卻沒有這樣的視覺回饋系統，而且在感覺和運動皮層都沒有活動。
