s Question Completion Status UESTION How do microglia impact neuronal function? They decrease the rate of firing and decrease synaptic adhesion molecules They decrease the number of synapses and increase synaptic adhesion molecules O They increase the rate of firing and increase synapse numbers O They decrease the rate of firing and increase synaptic adhesion molecules QUESTION 8 What would be a potential behavioral effect of increasing microglial numbers? O Animals would have impaired motor activity O Animals would have improved memory Animals would become less social O Animals would have impaired leaning QUESTION 9 Which of the following is false regarding the role of complement in the nervous system? O Knockout of complement proteins impairs the ocular dominance process in the LGN Complement has no effect on adult neurons Astrocyte signaling is necessary for complement upregulation in neurons O Complement tags synapses for removal by microglia

Explanation / Answer

7. Answer: D) they decrease the rate of firing and increase synaptic adhesion molecules

Microglial cells are the cells present in the immune system. These are highly sensitive to the changes taking place in the brain. These carry out an increase in synaptic adhesion, by the process of synaptic stripping, as there would be a damaged neural circuitry.
