Question

Researchers want to find out which brain region comes after brain region

c. to discover this, researchers can trace ________ axons using ________ labeling

Answer 1

The right answer is "afferent; retrograde". The afferent axons are the axons that carry sensory information from the whole body to the spinal column. Retrograde labeling is a research method in which neuronal connections are traced in a structure, starting at the termination point of the neuron until it reaches the source.
