Sumario: | Embryonic mammalian donor retina transplanted into the subretinal space of a mature host develops into a graft with wellorganized, but atypical retinal structure. We tested the effect of this organization on rabbitto-rabbit graft functional properties, isolating the graft to avoid contamination of graft responses by host retinal activity. Transient ON or ON-OFF spike-like responses and local electroretinograms (L-ERGs) were recorded simultaneously via a single electrode on the graft surface. These response components depended on stimulus diameter, sometimes in a way indicating antagonistic center-surround receptive field organization and spatial tuning (43%). Other times, the responses were an increasing function of stimulus diameter which saturated for large spots (57%). Response amplitudes were transplantation surgery is to be done with therapeutic aims. |
