Cerebral cortex

Anatomy of cerebral cortex: Brain is most complex organ in human body. The ability of brain for its functioning normally is manifestation of various activities it takes participation in various activities of day to day life, being it hidden from the view or perceptible, like walking, smelling, thinking, laughing, speaking, and hearing. These manifestations are results of very coordinated and complex electrical and chemical activity within and between the cells those makes up our brain. Abnormal…

The Localization of Brain Functions There are so many experiments to prove the theory of the brain, localization of brain functions.The main term 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…

Do we really use only 10% of our brain capacity to function in everyday life? It really depends on self opinion. Some of us may think we use more of our brain when we are working and some of us may think that when we are relaxing our brains are relaxing as well. There is no scientific theory behind how much we use of our brain. Most of us use our brains daily, to think, to react, to sense feelings, etc. You may be surprised on how much we use our brains each day. Its always active, axons are…

is a very common childhood mental disorder, with symptoms ranging from difficulty paying attention to general hyperactivity. Many previous studies have analyzed this mental disorder and have found correlations with a decreased size of the frontal cortex, along with abnormal activation of the basal ganglion; both of which help with cognitive processing and decision-making. While these may…

subcortical ischemic vascular disease (SIVD) or small vessel disease (SVD). A cerebral SVD/SIVD or cerebral microangiography is induced when blood circulation in arterioles is impaired. It can be easily distinguished by white matter lesions (WML) and lacunar infarcts. The Schaefer research aims to identify the changes in functional connectivity for SVD. Changes in functional connectivity in posterior cingulate cortex (PCC) and in the DMN are mentioned in the previous research. Schaefer 's study…

under the occipital bone. Damage to the occipital lobe can result in some major medical problems. Occipital lesions can cause visual hallucinations, vision cuts in each eye, and in more serious cases can lead to blindness due to holes in the visual cortex caused by lesions. Like the parietal and frontal lobes, the temporal lobe is responsible for many functions as well. The temporal lobe is associated with perception and Burton 3 recognition of auditory, memory, and speech stimuli. Visual…

certain labels for these bulges and grooves on the top of the brain. Decades of scientific data have unleashed the specific functions of the different regions 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…

stage is Memory Storage. In the 1950’s and 1960’s Karl Lashley and Wilder Penfield looked in to long term memories and where they are stored. Long term memories are not stored in just one part of the brain but are widely distributed throughout the cortex. Long term memories are stored throughout the brain as groups of neurons are cells within the nervous system that transmit information to other nerve cells, muscles or gland cells. Most neurons gave a cell body, an axon and dendrites.…

all human behavior is linked, somehow or someway, to the brain’s functions. According to the beliefs of these psychologists, each area of the brain influences different thinking and behavior. For example, language in humans is controlled by the cerebral cortex, but it contains two separate subsections. Broca’s area controls the production of speech and Wernicke’s area controls the comprehension of speech. Apart from the individual roles parts of the brain play, one’s behavior is also linked to…

various areas of the cortex and projected information to the primary motor cortex via thalamus, thus fine-tuning a movement (19). It was also believed that the Basal ganglia was involved with the inhibition and selection of action commands (19). These views suggest the involvement of both cerebellum and Basal ganglia(BG) in purely motor function. But that is not the case, recent studies have found a connection between the BG and cerebellum and projections from these areas to the cortex through…
