(Medical Xpress)—The ability to short-circuit debilitating tremors in disease states with implantable stimulators is nothing short of remarkable. The same can be said for cochlear prosthetics which restore hearing, and ...
Loss of neurons in in the retina due to trauma or disease leads to vision impairment or blindness, a process which is irreversible in humans. Interestingly, some animals like fish have the built-in ability to regenerate retinal ...
