Increment thresholds in normal and binocularly deprived cats.
Increment thresholds on a white background were determined for normal and binocularly deprived (BD) cats over a wide luminance range. Threshold vs intensity curves had a slope of unity for both groups but the increment threshold (delta I/I) for normal cats was 0.09 while increment threshold for BD cats was 0.60. Absolute threshold was reliably better in normal cats. the deficit of BD cats is considered a potential result of their abnormal cortical physiology and/or abnormal lateral geniculate physiology.
