The assumption that brain cells could not regenerate was based upon which characteristic of axons. Is it due to the perpheral nerous system or central nerous system?
The assumption that brain cells could not regenerate was based on the characteristic of axons in the central nervous system (CNS). Axons in the peripheral nervous system (PNS) have the ability to regenerate to some extent, while axons in the CNS have been traditionally believed to be incapable of regeneration. However, recent research has shown that there is some potential for limited regeneration of CNS axons under certain conditions.
