Cerebral Cortex Accounts for 80% of our brain’s volume Divided into two hemispheres connected by the corpus  callosum Divided into 4 lobes: Frontal Lobe-  associated with reasoning, planning,  producing speech, planning movement, interpreting  emotion messages, and problem solving  Parietal Lobe-  associated with movement and  orientation in space, object and facial recognition, and  tactile sensation Temporal Lobe-  associated with perception and  recognition of auditory stimuli, memory formation, and  understanding speech Occipital Lobe-  associated with visual processing

Hemisphere Symmetry In some functions, the left and right hemisphere are  relatively symmetrical The Primary sensory areas and Primary motor areas of  both the left and right hemisphere are symmetrical They are also  Contralateral,  which means that sensory  and motor messages to and from the right side of the  body are processed in the left hemisphere, and vice  versa However, some of the brain’s functions are  lateralized meaning that they are dominant in either the Left  hemisphere  or  the Right hemisphere

    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.
