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_forwardAccording to the somatotopic map of the primary somatosensory cortex (S1), the amount of sensory information received is proportional to the size of the body part it maps to.

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_forwardWould you expect the fingertips or the back to be represented by a greater area of the primary somatosensory cortex?Explainarrow_forward
- You are recording from a touch receptor in skin. When you stimulate a spot on the skin, the receptor fires continuously until you stop the skin stimulation. Which of the following pieces of information would you need to be able to identify what kind of receptor this is? Group of answer choices Whether the area of skin that can activate this receptor is big or small Whether the receptor sends its output to the somatosensory cortex or not You don’t need any more information; you can identify this receptor just from the information provided Whether the touch receptor is connected to an Alpha-Delta fiber or a C-fiberarrow_forwardFollowing administration of an opiate drug, "pain signals" are prevented from getting out of the spinal cord via two mechanisms. One inhibits spinal cord neurons that communicate with the parafascicular nucleus of the thalamus. What is the other way that pain signals are stopped? dendro-dendritic synapses that enhance IPSI's in somatosensory neurons. the disinhibition of long axons that start in the spinal cord and influence free nerve endings directly. O a feedback loop to the periaquedictal grey of the midbrain, which enhances neural activity in that area. axo-axonic synapses that prevents somatosensory neurons from releasing neurotransmitter.arrow_forwardTwo major somatosensory ascending pathways in the spinal cord, for touch and proprioception and pain and temperature, respectively, as discussed in class, are: gracile fasciculus; cuneate fasciculus dorsal column medial lemniscal system; anterolateral system posterior spinocerebellar tract; anterior spinocerebellar tract lateral corticospinal tract; anterior corticospinal tractarrow_forward
