PARIETAL LOBE AND THALAMUS 2 Parietal Lobe and frontal lobe In terms of a computer, the brain is the central processing unit. The brain controls senses, such as smelling, hearing, and vision. The brain receives signals from the body sensory organs (eyes, ears, nose, tongue, and skin) and then it sends it to the muscles. For example, when a person touches a hot surface, the brain processes that information and sends it to the neurons in the nervous system. The brain breaks down into four major parts: cortex, cerebellum, limbic system, and brain system. The cortex is the largest part of the human brain and it is linked to the production of high order functions. Some essential parts of the cortex are the functional lobe (reasoning, planning,thinking), parietal lobe (movement and perception), occipital lobe (visual), temporal lobe (memory, speech, and audiotrial information). The cortex is also divided into two hemispheres, left and right, and the corpus connects the two. There cerebellum is known as the little brain, the limbic is known as the emotional brain and is one of the oldest parts, and the brain stem produces basic functions such as breathing and heartbeat.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
