What are 2 different ways glutamate may be recycled? - Answer - It can be transported back into the cell by re-uptake transporters where it is stored into a synaptic vesicle. - Alternatively, it may be transported into a nearby glia cell where it is going to be broken down back to glutamine. The latter is later carried back to the neuron where it is synthesized back to glutamate and packaged into a synaptic vesicle. Which of these is the main excitatory neurotransmitters? - Answer Glutamate What is the cortical homunculus? (L2S11) - Answer It is a distorted representation of the human body where the different body parts are proportional to their representation in the somatosensory or motor neurological "map" (i.e., the bigger the chunk of the brain representing a body part, the bigger it will be in the homunculus representation). Which of the following is FALSE? - Answer Stimulation of the frontal lobes had a tendency to make patients short-tempered. It actually did not elicit anything deemed to be important. What is the difference in the function of the basal ganglia and cerebellum? (L2S13-16) - Answer - Both are involved in movement. - The cerebellum is important for fine-tuned movement. This is what allows us to have smooth and precise motion. - The basal ganglia is important for intended movement. It allows the voluntary initiation and cessation of movement.
