I accepted with no less trepidation than enthusiasm this generous offer and transferred my scientific attention forthwith to biederman ' s classical compendium on electrophysiology , and to the effects of electric currents more or less short of electrocution on the shape of the compound action currents of nerve 我接受這項美差時,即感到興奮也同樣誠惶誠恐,于是我把自己對科學的專注精神投給了關于電生理學的比德曼經典理論上, (具體的說)也就是投給了關于在不足以電致死的情況下電流增減對神經的復合作用電流形態的影響研究上了。

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征聯系起來的能力。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分辨率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。

Recently , research on the sos3 / athktl double mutants in arabidopsis showed functional disruption of athktl was shown to suppress t he salt sensitive phenotype of sos3 mutant indicating that wild - type sos3 may inhibit the activity of athktl as a na + influx transporter . but hitherto there is no evidences in electrophysiology about regulation of k + and na + influx by sos3 protein 結果暗示athkt1可能是一個na ~ +內流轉運體并起了調節k ~ + 、 na ~ +吸收系統的作用,并且野生型sos3蛋白可能抑制athkt1蛋白na ~ +內流轉運體的活性, athkt1可能是sos途徑的調節對象之一。
