全面而詳細(xì)地繪制出大腦皮質(zhì)的分工圖，使人們不勝驚奇的是，人的運(yùn)動和感覺功能在大腦皮質(zhì)上的投射是倒置的，而且一些運(yùn)動、感覺精細(xì)而靈巧的器官（如手和唇、舌等），比那些運(yùn)動和感覺較簡單而遲鈍的部分（如軀干），在大腦皮質(zhì)上投射的面積要大。緊接著，法國醫(yī)生布洛卡發(fā)現(xiàn)，右半身癱瘓的病人常伴有失語，死后尸體解剖發(fā)現(xiàn)病人是左大腦半球額葉有病變；而左半身癱瘓的病人不伴有失語癥，因此首先提出了“語言中樞”的概念，并把左半球稱為“優(yōu)勢半球”。習(xí)慣用右手的人（占90%左右），所有有關(guān)語言活動，如閱讀和書寫、理解和命名、計算和推理等功能都在左大腦半球。那么，右大腦半球（非優(yōu)勢半球）是否趨向退化呢？這是一個很有意思的問題。從左右大腦兩半球互相之間的來看，首先它們藉著一束強(qiáng)大的神經(jīng)纖維（約含2億條神經(jīng)）——胼胝體相連，互相交流兩半球的信息。這樣既有分工又是一個整體。70年代，美國科學(xué)家斯佩里和同事們做了裂腦手術(shù)——切斷胼胝，來治療一些用藥不能控制癲癇發(fā)作的病人，并做了許多非常精細(xì)的心理實驗，結(jié)果發(fā)現(xiàn)大腦兩半球有各自獨(dú)立的功能。它們分別是：左大腦半球有語言、閱讀、書寫及邏輯、推理、計算的能力；右大腦半球則有圖形、空間結(jié)構(gòu)的構(gòu)思能力，有音樂欣賞能力，及形成非言語性概念的能力。左大腦半球的思維活動是人類*的功能，由此可以說明人腦進(jìn)化、發(fā)展的一側(cè)化趨勢，也提示人腦存在著巨大的潛力大腦 中樞神經(jīng)系統(tǒng)的部分，也是腦的主要部分。分為左右兩個大腦半球，二者由神經(jīng)纖維構(gòu)成的胼胝體相連。被覆在大腦半球表面的灰質(zhì)叫大腦皮層。其中含有許多錐體形神經(jīng)細(xì)胞和其它各型的神經(jīng)細(xì)胞及神經(jīng)纖維。皮質(zhì)的深面是髓質(zhì)，髓質(zhì)內(nèi)含有神經(jīng)纖維束與核團(tuán)。在髓質(zhì)中，大腦內(nèi)的室腔是側(cè)腦室，內(nèi)含透明的腦脊液。埋在髓質(zhì)中的灰質(zhì)核團(tuán)是基底神經(jīng)節(jié)。大腦半球的表面有許多深淺不同的溝裂（凸處為回，凹處為溝）。其中主要的有中央溝、大腦外側(cè)裂、頂枕裂。人的大腦半球高度發(fā)展。成人的大腦皮質(zhì)表面積約為1/4平方米，約含有140億個神經(jīng)元胞體，它們之間有廣泛復(fù)雜的，是高級神經(jīng)活動的中樞。

Drawing a comprehensive and detailed picture of the division of the cerebral cortex makes one amaze the fact that the projections of motor and sensory functions in the human brain are upside down and that some organs, such as hands and lips, that feel fine and dexterous , Tongue, etc.), projected larger areas of the cerebral cortex than those that are simpler and less sensitive to exercise and feel (such as the trunk). Then, the French doctor Broca found that patients with paralyzed right hemiplegia often accompanied by aphasia, post-mortem autopsy found that patients with lesions of the frontal lobe of the left hemisphere; and paralyzed left half of the patient is not associated with aphasia, and therefore first proposed The concept of "linguistic hub" is called, and the left hemisphere is called the "dominant hemisphere." Right-handed people (around 90%) use all the linguistic activities such as reading and writing, comprehension and naming, calculation and reasoning in the left hemisphere. So, right hemisphere (non-dominant hemisphere) is the trend of degradation? This is a very interesting question. Judging from the connection between the two hemispheres of the left and right brains, firstly, they communicate with each other by means of a bundle of powerful nerve fibers (about 200 million nerves) - the corpus callosum. This division of labor is both a whole. In the 1970s, American scientist Sperry and his colleagues did a split-brain surgery - cut off the corpus callosum to treat some patients who could not control seizures with medication and did many very fine psychological experiments. They found that the two hemispheres of the brain had their own independent Function They are: the left hemisphere with language, reading, writing and logic, reasoning, computing power; the right hemisphere is the graphics, spatial structure of the ability to think, have the ability to enjoy music, and the formation of non-verbal concepts. The thinking activity of the left hemisphere is a human-specific function, which can illustrate the one-sided trend of human brain evolution and development, and also indicates that there is a huge potential in the human brain. The brain central nervous system is also a major part of the brain. Divided into two cerebral hemispheres, the two connected by the corpus callosum composed of nerve fibers. The gray matter that covers the surface of the cerebral hemispheres is called the cerebral cortex. Which contains many pyramidal neurons and other types of nerve cells and nerve fibers. Cortical deep medulla, medulla contains nerve fiber bundles and nuclei. In the medulla, the interior of the brain is the lateral ventricle, which contains transparent cerebrospinal fluid. The gray matter nucleus buried in the medulla is the basal ganglia. The surface of the cerebral hemispheres have many shades of different shades (convex at the back, the recess for the ditch). The main central ditch, the lateral cerebral fissure, the top of the occipital crack.
