Cerebral cortex is divided into four important lobes which is the frontal lobe, temporal lobe, occipital lobe and parietal lobe. These are the first areas of the cerebral cortex to receive signals from each of the senses. The first lobe is frontal lobe which is located at the front of the brain. This lobe works in reasoning, motor skills, higher level cognition and expressive language. The motor cortex is located at the back side of the frontal lobe. The motor cortex is important in receiving and utilizing the informations from other lobes to carry out body movements. Any damages can caused a person to changes in sexual habits, socialization, attention and increase in risk-taking. The second lobe in our brain is the temporal …show more content…
Corpus callosum is the larger white matter structure in humans brain because it is made up of more than 200 million fibres (Paul M. Thompson, 2007) which connecting the two hemisphere by giving or transmit signals. According to Regina Bailey, a biology expert said that the corpus callosum is a thick band of nerve fibres that divides the cerebrum into left and right hemispheres. It connects the left and right sides of the brain allowing for communication between both hemispheres. The corpus callosum transfers motor, sensory, and cognitive information between the brain hemispheres (Regina Bailey,2013). Based on the case, a study was done led by Weiwei Men of East China Normal University, a revolutionary technique is created to explore the ‘internal connectivity’ of Einstein’s brain via the corpus callosum. It is also said that a thicker corpus callosum suggest that there are a greater number of neurons and different regions of the corpus callosum are implicated in a variety of special …show more content…
According Caminiti, the posterior (back) portion of the corpus callosum is called the splenium; the anterior (front) is called the genu (or "knee"); between the two is the truncus, or "body", of the corpus callosum. The part between the body and the splenium is often markedly narrowed and thus referred to as the "isthmus". The rostrum is the part of the corpus callosum that projects posteriorly and inferiorly from the anteriormost genu, as can be seen on the sagittal image of the brain displayed on the right. The rostrum is so named for its resemblance to a bird's
