額猴 的英文怎麼說
中文拼音 [éhóu]
額猴
英文
uakari monkey-
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。There exists deficit of executive control in schizophrenia, attention deficit hyperactivity disorder, obsessive - compulsive disorder ; tourette syndrome, conduct disorder, anti - social personality disorder and so on. in a word, the pfc is very important when behavior must be guided by internal states or intentions
近年來神經成像技術日漸增多，研究顯示腦能量代謝的各個環節均與心理過程密切相關，猴在執行go / nogo任務過程中，主溝、前後額極和頂-枕皮層都有明顯的區域性腦血流（ rcbf ）增加，說明這些腦區參與了go / nogo任務。Recently neuroimaging technique was used extensively and found that there is close relationship between brain energy metabolism and psychological process. pet research shows there are increase of regional cerebral blood flow in prefrontal, occipital and parietal cortices during go / no go discrimination tasks in the monkeys. but it is not clear about the neurochemistry mechanism of executive control
二、恆河猴執行控制功能的腦能量代謝（ pet ）特點恆河猴執行go / nogo任務時前額葉皮層、運動皮層、扣帶皮層、后頂葉皮層等多個腦區均有激活，其中前額葉皮層激活最明顯，提示執行控制由多個腦區共同完成，前額葉是執行控制的重要腦區。These suggest that the inhibition of gaba is a key point in executive control of behavior. the non - competitive antagonist of nmda / glutamate receptors has recently been shown to induce schizophrenia - like symptoms in healthy volunteers and in schizophrenic patients
主要結果和結論如下:一、恆河猴前額葉執行控制功能的行為和生理學特點1 .三隻猴執行go / n090任務的反應時分別為419士18ms 、 376士26ms和540士21ms 。分享友人
