Studying regeneration in the central nervous system (CNS) is hampered by current histological and imaging techniques because they provide only partial information about axonal and glial reactions.

The spinal cord is a long bundle of nerves and cells that extends from the lower portion of the brain to the lower back. Spinal cord functions include carrying signals between the brain and the rest ...

Several studies have demonstrated that SPIO-labeled stem cells migrate into a brain or spinal cord lesion after transplantation; MRI detection was confirmed by histological analysis with iron staining ...

Fluorescence imaging can reveal details of neuronal activity in sections of the spinal cords of animals, but collecting data from living subjects can be challenging. Developments in micro-optics ...
