Figure 6. Control AON-S Ganglion Cell Receptive Fields Retain Widths with Partial Stimulation.

Figure 6.

(A) Spatio-temporal receptive field obtained from voltage responses of a control AON-S ganglion cell in current clamp. Receptive field obtained with a (left) full bar noise stimulus and (right) partial bar noise stimulus with every other bar held constant at the mean intensity. Receptive fields measured from the same cell. Red and blue represent opposite polarity responses.

(B) Spatial receptive field for the same AON-S ganglion cell depicted in (A) either with full (black) or partial (maroon) stimulation.

(C–E) Gaussian fit parameters for receptive fields measured with full and partial stimulation within the same control AON-S ganglion cells: (C) 1 SD center width, (D)1 SD surround width, and (E) center-to-surround weights. None of these parameters are significantly different between full and partial stimulation.

(F) Time to peak of temporal receptive fields. Individual cells (open circles) and median ± IQR (closed circles ± error bars). Dotted line represents line of slope unity. Slowing of the time to peak is the only parameter that partial stimulation of control retina mimics of the DTR condition (Figure 5).
