Cerebral cortex

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 white matter, consisting mainly of the white myelinated sheaths of neuronal axons. Magnetic resonance imaging (MRI) of the brain makes it possible to measure the thickness of the human cerebral cortex. It varies the thickness of different cortical areas…

The cerebral cortex is formed up of overlapped and intertwined gray matter in the cerebrum of the brain. It is associated with the superior brain functions, coordination of sensory information, the capability to gain knowledge, the consciousness of being able to receive memory, along with the expression of originality, therefore playing an essential part in our consciousness. The cerebral cortex consists of very small layers of cells composed of billions of neurons as well as their endless…

The cerebral cortex is defined by Kalat (2014) as being the most prominent part of the forebrain, consisting of multiple layers of cells that are located on the exterior of the cerebral hemisphere. These layers of cells consist of either white matter or gray matter, as well as the axons that transfer information with neurons, either through the corpus callosum or the anterior commissure, and connect both the right and left hemispheres of the brain (Kalat, 2013). The cerebral cortex contains six…

6) The monoamine theory of depression foresees the underlying pathophysiologic source for depression is the diminution of levels of norepinephrine, serotonin, and dopamine within the central nervous system (National Center for Biotechnology Information). Indication for this hypothesis is sustained with clinical trials and animal testing. Barchas, J., and Altemus, M.

David C. Van Essen is one of many connectome projects across the globe. Dr. Van Essen engineered the human connectome project from a previous study two decades ago where he and his collaborators from California Institute of Technology mapped the connections of the visual areas of the Macaque monkey. Inspired by his Macaque monkey research, Dr. Van Essen transferred his academic curiosity to the human brain and its trillion synapses. After receiving two grants from the National Institute of…

The Cerebellum and its connection to autism Many scientists and researchers have accredited one of the causes of autism to the reduced number of Purkinje cells in the cerebral cortex. Purkinje cells play a vital role in the transmission of signals to the cerebral cortex that control Purkinje cells are what make practice perfect because they can be condition with lots of repetitive movement, which can explain the importance of routine for most kids with autism (Purves, Augustine, Fitzpatrick,…

The following data collected has brought me to the conclusion of using the elephant as the base because it is bigger than the gorilla Brain which is more like a chimpanzee meaning it has more human characteristics, this was huge plus in the making of our brain because this gives us more of a insight in how we were to construct the model. Once more proving to have two incredibly smart animals here are a few ways they use their brain in important ways. Gorilla brains basically work like human…

The human brain is very fascinating. It has many parts and functions, which help us in our daily lives. The brain is one of the most important things we humans have. The human brain has four parts: Hindbrain, Midbrain, Forebrain, and Cerebral Cortex. With each part comes its functions. For hindbrain the parts are medulla, cerebellum, and pons. For forebrain the functions are the limbic system, thalamus, hypothalamus, basal ganglia, and cerebral cortex. And last the cerebral cortex, the sections…

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 level of the hindbrain and just above the medulla, they serve as a bridge and information from higher parts of the brain revels through these to get to the…

cord, muscles, reflexes and receptors. The act of walking begins from brain and spinal cord which is the planning on how to walk. More precisely, it starts from the cerebral cortex. Cerebral cortex is the region of decision-making and it initiates voluntary response, in this case, the act of walking. Basal ganglia are also responsible for voluntary locomotion. It requires the knowledge of the body’s position in space (where am I walking to) and what movement should be made (should I walk) and…
