Document Summary

Video: to prevent epilepsy, separate corpus collosum (nerve fibres that connect the left brain to the right brain). Left side of the brain cannot communicate with right side of the brain. What you see is different, and describes differently. This cancels out effect of other neuron: measurement error. Projection areas: topographic representation, contralateral control, functional assignment of space. Topographic representation is mapping on brain surface that corresponds to part of body that you want to move. There is no equal assignment of space: for motor cortex, there is much more brain tissue devoted to face than to knee/ankle/toes. This is because face=used for language, other things, therefore we need to devote more motor control to face. Most motor control=devote to hands and face. Contralateral control: there is opposite side control in each hemisphere: right hemisphere controls left side of body, and vice versa.
