The left side of the figure illustrates the retina transplantation procedure. The right side of the figure represents examples of orientation tuning curves recorded from three rats: a normal rat, a rat with a transplant and a rat with a degenerated retina (blind). Displayed below the tuning curves are the responses to sinusoidal grating stimuli. The response patterns indicate that neurons in the brains of transplant recipients are very similar to those of the rats with normal vision.
Researchers from the University of California, Irvine School of Medicine, have discovered that neurons located in the vision centers of the brains of blind rats functioned normally following fetal retina cell transplants, indicating the successful restoration of vision...
