What are the neural mechanisms responsible for CAPD? Klug: Neurons, the cells in the brain, talk to each other with what’s called action potentials, little flashes of electricity, and they run between cells through axons. The axons have insulation – a fatty sheath – that’s called myelin. And when that gets damaged, problems occur. Your novel treatment is a combination of an FDA-approved remyelinating agent and an acoustic therapy developed in the Klug Lab. How did you arrive at this treatment?
