Revival of light signalling in the postmortem mouse and human retina

Death halts circulatory, respiratory, and brain functions, limiting the viability of central nervous system tissues for transplantation. However, groundbreaking research on the retina reveals rapid neuronal decline postmortem, yet also identifies conditions for potential revival. Even after death, human macular photoreceptors retain light responsiveness, challenging notions of irreversible neuronal death and offering insights for visual rehabilitation.
