The projections from the hand will still be there, but will be inactive. The projections from the hand will die, and that area of the cortex will be empty. Projections from the face and neighboring limb will expand to control that cortical area. That cortical area will die.arrow_forward

The degree to which language shows hemispheric lateralization is affected by whether someone is left-handed or right-handed. All of the answer options are true about hemispheric lateralization. In terms of lateralization function, individual people tend to be more right-brain (creative) or left-brain (scientific). Birds can show hemispheric lateralization when it comes to bird songs. For humans, the emotional component of language is more often influenced by the right hemisphere.arrow_forwardThe limbic system is composed of several interconnected structures including the olfactory bulbs, amygdala, hypothalamus, hippocampus, parahippocampal gyrus, cingulate gyrus, subcallosal gyrus, septal nuclei, mammillary bodies, and the thalamus. Pair each of these structures with their function listed below: -This limbic area is active when you are trying to memorize the names of brain areas. It is also severely atrophied in people suffering from late stages of Alzheimer’s Disease. -This limbic area is active when you are watching something that makes you feel sad. -This limbic area is active when you feel thirsty. -When the activity of this limbic area is increased you feel a sense of pleasure. -When this limbic area is damaged it often results in patients experiencing anterograde amnesia. -Damage to this limbic structure while rare often results in patients going into a coma. -This cortical limbic structure plays a large role in motivation and movement and has recently been…arrow_forward
