Question

Quizplus · Accepted Answer

Both myelin stains and horseradish peroxidase can be used to study the pathways of the brain. Myelin stains highlight the myelin sheaths surrounding axons, allowing for visualization of the white matter tracts that connect different areas of the brain. Horseradish peroxidase can be injected into a specific area of the brain and the spread of the enzyme can be traced to visualize the connectivity of that region.
