Cerebral Cortex

 

The cerebral cortex also known as the cerebrum is the wrinkled part outer layer of the brain. The cerebral cortex is the largest part of the brain which is located behind the forehead.  (Brain Regions and Their Functions – Buzzle Web Portal … (n.d.).) The cerebral cortex is divided into two areas the left and right hemisphere. The cerebral cortex affects functions such as thinking, planning and fine motor skills.

I have a personal experience regarding the functions of the cerebral cortex. In 1982, after being struck in the head with a baseball bat, I suffered a subdural hematoma to my left hemisphere of my cerebellum. The blood clot grew and began to create pressure between my skull and my brain. The trauma to my left hemisphere of my brain affected the right side of my body. After several hours, I began to experience severe headaches and after twelve to twenty-four hours, I began to experience lost of motor movement, coordination, balance and equilibrium. I first noticed my coordination was affected while I was having breakfast. I attempted to grab my cup of tea by the handle; however, my hand would miss the handle to the left and to the right. I began to focus on the handle of my cup and attempted again to grab the handle and once again my hand would miss the handle to the left and to the right. Noticing that I could not grab my cup, I guided my affected hand with my non affected hand to the cup and once again I could not physically grip the handle or I believe I could feel the sensation of my hand gripping the cup. I went to went to the emergency room and was immediately admitted for emergency surgery. After the surgery, the doctor stated to me that if I had waited any longer, I would have suffered permanent disability.

The cerebellum contains millions of neurons that facilitate processing data. Neuron via synapse relays information between neuron, body muscles and areas of the cerebral cortex that are involved in motor control. Any type of head trauma to the cerebral cortex or the cerebellum will great affect motor movement coordination, balance, and equilibrium.
