The Areas can be split into 3 groups__________ Areas
________________________________________ for impulses from ______
cerebrum/cerebral hemispheres ________ of the cerebral hemispheres receive impulses from _____ organs and transmit them to the ____________ areasThe _______ areas of the cerebral hemispheres receive _______ - _______ them in the light of similar past experiences and transmit impulses to _____ areasThe motor areas transmit impulses to the _______The size of the ______ and ______ areas is related to the number of __________ in that areaThe left and right cerebral hemispheres control the _________ sides of the body
