Cerebral hemisphere

The divide between the Northern and Southern Hemispheres has developed into a problem where the Southern Hemisphere is becoming further behind on the economic and social scale because they are less developed. As the Northern Hemisphere exploits and profits off the raw goods that the South produces. This creates a gap where they North is always expanding its economy and the Southern Hemisphere is currently staying in the same place. This system favors the countries that have the ability to…

The cerebral cortex has deep grooves called fissures that separate some regions. The longitudinal fissure separates the left cerebral hemisphere from the right cerebral hemisphere. On the other hand, the transverse cerebral fissure separates the cerebral hemispheres from the cerebellum. The cerebral cortex contains three kinds of functional areas: Motor areas, sensory areas, and association areas. The…

The structure of the cerebral cortex The cerebral cortex is the cerebrum’s outer layer. It is divided into two cortices, the left and the right cerebral hemispheres divided by the medial longitudinal fissure. The cerebral cortex plays a major role in memory, attention, perception, awareness, thought, language, and consciousness. The human cerebral cortex is thick about 2-4mm.The cerebral cortex is gray matter, consisting mainly of cell bodies and capillaries. It contrasts with the underlying…

of the brain. Below the cerebral cortex or top of the brain, connects fibers between neurons forming a whitish look otherwise known white matter. The cerebral hemispheres have several types of fissures. By pin pointing the top of the brain, it can effectively be separated into pairs of so called lobes. Lobes are just small regions of the brain. The cerebrum or brain can be separated into different pairs of frontal, temporal, parietal or occipital lobes. Every hemisphere has a frontal, temporal…

At a first glance, hemispheres look like mirror images (identical). However, science has been proving since 1968 effectively through examinations of positron emission tomography (PET), functional magnetic resonance imaging (fMRI), electroencephalography (EEG) and regional cerebral blood flow (rCBF), the existence of anatomical asymmetries, neurochemical and functional, thereby designating the hemispheric specializations. Paul Broca (1860), through work and biopsies found that the language…

The lateralization of brain function refers to how some functions, or cognitive processes tend be more dominant in one hemisphere than the other (Sperry, 1968). The medial longitudinal fissure splits the human brain into two distinct cerebral hemispheres, joined by the corpus callosum (Gray, 1985). The two hemispheres demonstrate strong, but not comprehensive, bilateral symmetry in both structure and performance. Handedness is not a single variable, but can be placed in a spectrum of 4 separate…

and internal organs. The largest part of the brain is called the cerebrum. The cerebrum is divided into two cerebral hemispheres, which develop from the forebrain. The hemispheres have the cerebral cortex which contains ten billion nerve cells. Underneath is the brainstem, and behind that is where the cerebellum is. The outermost layer of the cerebrum is the cerebral cortex is divided…

that is about the theory is lateralization. Lateralization can be described as that localization of brain functions on the different parts of brain. Basicly, brain has two hemisphere, left and right. According to this, left hemisphere controls right side of the body, right hemisphere controls left side of the body. Both hemisphere have also some specific parts that have different jobs and this jobs can not be done by another part. Brain localization theory is proven by experiments so far.…

particularly interesting is the hemispherectomy. The surgical procedure is performed on children with severe and uncontrollable seizure disorders and consists of removing an entire hemisphere of the child’s brain. Remarkably, the hemisphere of the brain left intact will begin to acquire the tasks of the removed hemisphere and the child will improve to live a relatively normal life. The procedure is often times done to young children because their brains are still developing and can adapt. Thus,…

The main three sections of the brain are the hindbrain, the limbic system, and the cerebral cortex. The hindbrain consists of the medulla which is directly above the spinal cord and controls breathing, heartbeat, and other vital life functions like the things we don’t have conscious control over. It also has pons which are in the uppermost…
