Question

Quizplus · Accepted Answer

Horseradish peroxidase stain is a tracing technique that can be used to identify and label the location of the origin and endpoints of a pathway. It involves injecting the enzyme HRP into a specific area and tracking its movement as it travels along the pathway to its endpoints, which can be visualized by staining with a chromogen. This technique is widely used to study neural pathways in the brain and spinal cord. The other stains listed, Golgi silver stain, Nissl stain, and myelin stain, are not tracing techniques and would not provide information on the origin of a pathway.
