Contrast efferent and afferent tracing procedures
What will be an ideal response?
Answer: In the efferent tracing procedure, a chemical such as PLA is injected into a brain site, taken up by dendrites and transported out to the axons. Immunocytochemistry is used to visualize the places that receive axons from the neurons of the injection site. In contrast, afferent tracing involves injecting a chemical, such as fluorogold, which is taken up by axon terminal buttons and transported backwards to the cell bodies. This procedure thus identifies the neurons that innervate a specific brain region.
