QUESTION 7 What would be a potential behavioral effect of increasing microglial numbers? Animals would have impaired learning Animals would become less social Animals would have improved memory Animals would have impaired motor activity QUESTION 8 Which evidence supports the idea that CNS neurons, besides motor neurons, can support axon growth and repair? Hypoxia leads to an increase in cytochrome c release from the mitochondria Chronic traumatic encephalopathy increases deposits of tau protein in the cortex Peripheral grafts can support regrowth in the optic nerve. Ischemia causes a cellular cascade that leads to an increase in expression of Bcl2. QUESTION 9 How do microglia impact neuronal function? They decrease the rate of firing and decrease synaptic adhesion molecules They increase the rate of firing and increase synapse numbers They decrease the rate of firing and increase synaptic adhesion molecules They decrease the number of synapses and increase synaptic adhesion molecules
