Step One

The Cortex

 Also known as the cerebral cortex, this part of the brain is located in the outer layers of the human brain. It is characterized by wrinkled features. The central areas of the cerebral cortex are subdivided into sections with specified functionalities such as vision, hearing, smelling, and feeling. More so, this particular part of the brain regulates sophisticated functions such as making a speech, thought processing, and memory. The entire brain is made up of two even cerebral hemispheres connected via the callus. Also, the outer part of the cortex is wrinkled and differentiated by its furrow-like features. Even though the two cortex hemispheres are similar, they have different functionalities (Hagmann et al., 2008). Each cortex hemisphere control one side of the human body. For instance, the right hemisphere regulates the left body and the left hemisphere is in charge of regulating the right body. The left hemisphere enables functions such as speaking, scripting, composing music or sentences, and finding solutions to challenges. The other half of the left cortex hemisphere is facilitating the analytic thinking process. The right cortex hemisphere enables synthetic thinking. At the central part of the cortex, the hemisphere is the basal ganglia which start and control motion. Experts claim that the reason the cortex is wrinkled is due to the limited skull space. Hence the wrinkles allow it to fit into the skull and at the same time retain its volume. From a general perspective, the cortex covers the inner parts of the brain and it is 1.5mm to 5mm thick. Physically it is grey and experts refer to it as the grey matter (Jones, 2015). The cortex is grey because of its isolation and uninsulated nerves hence making it grey unlike the other insulated parts of the brain which are white due to their white linings the cortex covers the lining. It is vital to note that the cortex covers the cerebellum section of the brain and makes up most of the brain total mass.

The shown above the cortex is the outer layer of the brain and its covering protects the innermost sophisticated or delicate subsections of the brain. The fold or wrinkles within the cortex are usually referred to as minges.  The motor cortex is located in the middle of the brain where the primary motor cortex produces neural impulses that initiate motion. The premotor cortex is found next to the primary motor and contributes to movement regulation. The supplementary motor section enables the formulation and production of motions, organizes motion sequences, and directs both sides of the body (Hagmann et al., 2008). It can be found within the midline layer near the anterior hemisphere. Most of the neurons within the motor cortex indicate and communicate with the spinal code synapse hence allowing the entire section to function as a whole. The incorporation of muscles and joints sometimes overlap and significantly help the cortex at an optimal range. Before evaluating any brain activity, neuroscientists have to isolate and examine the cortex as a separate entity and then confirm that it functions clearly and accurately.  The cortex part of the brain influences moods, feelings, taste, and how humans learn (Serre et al., 2007). Well, known mechanisms somehow such as the electroencephalography can record neuron impulses within the brain and signal on a computer which parts of the cortex are not functioning properly.
