Fig. 6. Intracellular recordings from a spectrally opponent ganglion cell (G81L3C1) that showed opponency between ultraviolet and blue. Upper trace: responses to a spot stimulus at the receptive field centre (radius, {phi}=300µm) were hyperpolarizing to ultraviolet (370nm) and red (640nm) and depolarising to blue (450nm) and green (540nm) flashes. Lower trace: responses to an annulus ({phi}ext=1500µm, {phi}int=1050µm) reversed the polarity to red flashes, relative to the centre responses, but not to ultraviolet, blue and green flashes. Therefore, the cell presented spatial opponency only to red stimuli.
