Contralateral: the right side of the brain controls the left side of the body and the left side of the body controls the right side of the body. Connected by corpus callosum: allows each hemisphere to communicate with each other. Differences in right and left hemisphere function: right: images and spatial relations. Being able to mentally rotate objects and tell whether it is the same object. Estimating direction and distance: left: language, reading, writing, understanding and producing speech. Serving the corpus callosum produces a split brain. Left hemisphere: the interpreter (tries to make sense of mix-up) I picked up the spoon because i"m going to have some soup. : parietal lobe touch; contains somatosensory cortex, more sensitive skin regions have larger cortical areas. Damage to right parietal lobe results in hemi-neglect (impaired left visual field) Divide into four lobes: parietal lobe touch, occipital lobe vision, temporal lobe hearing and speech comprehension, frontal lobe movement, planning, abstract thinking, impulse control.
