Proximal edge | Distal edge |
---|---|
a1 = 0.788 | a2 = 0.367 |
b1 = 1.20 | b2 = −1.16 |
c1 = 1.03 | c2 = 1.04 |
The nonlinear regression was performed over 5239 data points (R2 = 0.63; p < 0.001). The Gaussian with constants a1, b1, and c1 results in the response peak corresponding to the stimulus location of ∼y = 1 mm (refer to Fig. 5), at which point the proximal edge of the annular segment is over the receptive field. For each of the Gaussians, the constant b represents the offset, and the constants a and c determine its width and height, respectively.
