Diffusion spectrum imaging can produce three-dimensional images of the neural pathways that connect one part of the brain to another. These neural pathways, made up of bundles of myelinated axons, are sometimes called:
A) diffusions.
B) tracts.
C) the reticular formation.
D) action potentials.

Question

Quizplus · Accepted Answer

Neural pathways made up of bundles of myelinated axons are called tracts. Diffusion spectrum imaging is a technique that produces three-dimensional images of these tracts. The reticular formation is a network of neurons in the brainstem, and action potentials are electrical signals that travel along neurons, but neither of these terms accurately describes the bundles of axons that diffusion spectrum imaging can visualize.
