You are recording from some neurons in the pulvinar nucleus in the thalamus and want to know where neurons in that nucleus project. What is/are the best method(s) to use to determine this? Select all that apply.
A) Use a retrograde tracer in the pulvinar nucleus
B) Use a retrograde tracer in the cortex
C) Use an anterograde tracer in the pulvinar nucleus
D) Use an anterograde trace in the cortex
E) Use diffusion tensor imaging (DTI)

Question

Quizplus · Accepted Answer

An anterograde tracer is injected into the cell body located in the pulvinar nucleus and then moves down the axon to the terminals. Retrograde tracers would label neurons that project to the pulvinar nucleus. DTI only shows fiber tracks and does not label specific projections.
