Depth-dependent contrast gain-control
Contrast adaptation that was limited to a small region of the peripheral retina was induced as observers viewed a multiple depth-plane textured surface. The small region undergoing contrast adaptation was present only in one depth-plane to determine whether contrast gain-control is depth-dependent. After adaptation, observers performed a contrast-matching task in both the adapted and a non-adap...
متن کاملParaproteinemia and Kidneys – from Henry Bence Jones till Now Days
Urol Nephrol Open Access J 2016, 3(3): 00078 On addition of nitric acid, it effervesces, assumes a reddish hue, and becomes quite clear, but as it cools, assumes the consistency and appearance which you see. Heat reliquifies it. What is it?” Dr Henry Bence Jones tested the urine sample himself and presumed that the substance, defining unusual properties is “deutoxide of albumin”. Now we know th...
متن کاملThe statistical computation underlying contrast gain control.
In the early visual system, a contrast gain control mechanism sets the gain of responses based on the locally prevalent contrast. The measure of contrast used by this adaptation mechanism is commonly assumed to be the standard deviation of light intensities relative to the mean (root-mean-square contrast). A number of alternatives, however, are possible. For example, the measure of contrast mig...
