Furthermore, the receptive field of J-RGCs is unusual in that the integrated strength of its ON surround exceeds that of the OFF centre. Kim et al. reached this conclusion after recording the response of J-RGCs to different sizes of flashing light spots centered at the soma (cell body). When the flashing spot was of a certain large enough size, the J-RGC sometimes failed to respond. Upon increasing the size of flashing spot even further, Kim et al. found that the J-RGCs tended to respond at light onset. Thus the strength of the JAM-B cells' ON surround exceeds that of their OFF center--an unusual feature in a retinal ganglion cell.
