Document Summary

Communication from one side of the brain to the other happens by the corpus callosum: corpus callosum: bundles of axons that allows communication from one side of the cortex to the other. Some left-handers have language areas located on the right side of their brains, or on both sides: most people specialized language areas exist only on the left side of the brain. Wer(cid:374)i(cid:272)ke"s a(cid:374)d bro(cid:272)a"s areas are lo(cid:272)ated o(cid:374) the left side. Roger sperry: split-brain patients people who have undergone a surgical procedure to treat severe epilepsy. In this surgery, the corpus callosum is split to stop the spread of seizures from one side of the brain to the other: after the surgery patie(cid:374)ts (cid:272)a(cid:374)"t i(cid:374)tegrate i(cid:374)for(cid:373)atio(cid:374) fro(cid:373) the t(cid:449)o he(cid:373)ispheres. Meaning the two hemispheres require the corpus callosum to communicate. More general thought processes are lateralized: people who think a certain way use one side of their brain more than the other.
