Does not mean that only one hemisphere is involved in certain type of cognitive processing. It means that the majority of a certain type of processing occurs in one hemisphere. Corpus Callosum - Allows communication between the two sides of the brain. Contralateral Organization - A stimulus present to the left visual field (or body) is projected onto the right hemisphere( and vice versa). So basically how the left side of the brain controls the right side of the body. Regions of Posterior to CS and FS - Responsible for sensory inputs Frontal Lobe - Motor output and higher cognitive functions Split Brain Patient - - The corpus callous has been surgically severed - The L and R hemispheres do not communicate Research on Split Brain Patients - Used to learn about the specialization of the two halves of the cerebral hemisphere Experimental Design for Split Brain Experiment - 1. Subject sits a certain distance from a screen and fixes eyes on a plus sign in the center of the screen 2. Anything shown to the R of the plus sign goes only to the LH and vice versa.

He can say the word "Ship" since speech is in the LH. Ex 2: Phone + _______ Left Visual Field goes to RH. He can't say the world "phone" but he can draw it. Once he draws it, he can say the word (this is the communication outside of the brain part). Processing it visually, not as a word so he can't write the word, he needs to draw it. "He didn't see it" but he obviously did if he can draw it. He wasn't aware he saw it. Split Brain: Experiment 2 - Two words are flashed simultaneously -- each to only one half of the brain Ex: Toad + Stool Results: Joe draws the toad first b/c it goes to the RB (Sp
