Effect of stimulus-detector mismatch.

<p>Modelled direction discrimination performance with an RDK and right vs left motion for 220 arcmin displacement size and two dot densities (500 dots – filled triangles and solid line; 4000 dots – filled squares and dashed line) as a function of the mismatch between the local detector’s catchment area separations and the stimulus’ dot displacement. Lines are fits of Gaussian functions to the data.
