The results showed : ( 1 ) the forming sequence of the cortex plate in different types cortex in goat fetus is from paleocortex and neocortex to archicortex , which is contray to the law of phylogeny 不同類型大腦皮質(zhì)皮質(zhì)板的分化順序為古皮質(zhì)舊皮質(zhì)新皮質(zhì),與種系發(fā)生的順序相符。
Har1 is expressed before birth in the developing neocortex ? the outer layer of the brain that seems to be involved in higher functions such as language , conscious thought and sensory perception Har1在妊娠期的新皮質(zhì)? ?大腦的外層,可能同語言、意識思維和感知等高級功能有關? ?發(fā)育期間開始表達。
Together these sensory organs are supplied by more than 100 , 000 nerve fibers that carry information to the central nervous system and eventually to the highest mammalian processing center , the neocortex 共有10萬條以上的神經(jīng)纖維支援這些感覺器,把訊息傳到中樞神經(jīng)系統(tǒng),最終抵達哺乳動物的最高層處理中心,即新大腦皮質(zhì)。
We have used a theoretical " learning rule , " devised to account for experience - dependent shifts in neuronal selectivity , to guide experiments on the elementary mechanisms of synaptic plasticity in hippocampus and neocortex 實驗解果顯示,許多大腦海馬回與新皮質(zhì)突觸可進行雙向性改變,且此變化可長達幫助長期記憶儲存的功能。
Topics include : functional neuroanatomy and neurophysiology , sensory and motor systems , centrally programmed behavior , sensory systems , sleep and dreaming , motivation and reward , emotional displays of various types , " higher functions " and the neocortex , and neural processes in learning and memory 包括以下單元:功能性神經(jīng)解剖學及神經(jīng)生理學、感覺與運動系統(tǒng)、中樞主導之行為規(guī)劃、感官系統(tǒng)、睡眠及造夢、動機與回饋、多重情感表現(xiàn)、 “較高級功能”及大腦新皮質(zhì)、學習與記憶行為中的神經(jīng)程序。
The results showed that the expressions of il - 1 receptor type 6 tt i in normal adult rat brain were very widely , and there were intense immuno - positive cells of il - 1 receptor type i in septal area , medial preoptic area , neocortex , hippocampus , paraventricular nucleus of the hypothalamus , supraoptic nucleus , hypothalamic ventromedial nucleus , arcuate nucleus and median eminence 結(jié)果顯示:型il - 1受體在正常成年大鼠腦內(nèi)有廣泛的表達,隔區(qū)、視前內(nèi)側(cè)區(qū)、新皮質(zhì)、海馬、下丘腦室旁核、視上核、下丘腦腹內(nèi)側(cè)核、弓狀核和正中隆起等部位有較多型il - 1受體陽性的細胞。
The predominantly expressed nr2 subunits in hippocampus and neocortex are nr2a and nr2b , they have different developmental expression profiles - there is a developmental decrease in expression of the nr2b subunit and an increase in expression of the nr2a subunit , which endow the nmda receptor with distinct channel properties 而隨著年齡的增長, nr2a亞單位的表達量和突觸含量逐漸增加。不同的nr2亞單位賦予nmda受體不同的通道動力學特性,如在老年動物中觀察到nr2b向nr2a亞單位的轉(zhuǎn)換降低了突觸可塑性。
