Critical flicker frequency in monocularly deprived cats.
Critical flicker frequency (CFF) was determined for both eyes of long-term monocularly deprived (MD) cats over a wide luminance range. Although MD cats could discriminate flicker before and after lid opening, CFF of the deprived eye (30 Hz) was much lower than CFF of the non-deprived eye (40 Hz) and the CFF of the non-deprived eye was lower than a normal cat's monocular CFF (58 Hz). The CFF deficit of the deprived eye became less pronounced at low luminance levels. The observation (and magnitude) of a CFF deficit for the deprived eye is compatible with the reports of a Y-cell loss in LGNd. The CFF deficit of the non-deprived eye has no obvious explanation.
