WebMay 20, 2024 · Focal axon swelling refers to localized swelling in axons that may occur because of trauma (e.g., traumatic brain injury) or neurodegenerative diseases (e.g., Alzheimer’s disease). Since the swelling region can be many times larger than its original axon size, many researchers hypothesize that the swelling can alter the action potential …
