Description

The study shows that a single coelenterazine dose leads to functional recovery measured 4 weeks post-injury, yet the duration of bioluminescent activity and neuronal excitation from CTZ is typically much shorter. This temporal disconnect between brief treatment and prolonged benefit suggests unknown sustained cellular changes that warrant investigation.
