The responses elicited by different stimulus intensities and sizes were recorded from visually deprived LGN neurons of cats. These data were compared with similar data collected from normal cats (Winters and Hamasaki, 1972). Approximately 60 per cent of the visually deprived units were classified as abnormal. These units were characterized by (1) lower firing rates, (2) longer latency, (3) absence of a rise in threshold with targets which overlap the peripheral region of the RFC and (4) flatter intensity-response curves. These properties are similar to those found in an earlier study of visually deprived LGN neurons (Hamasaki et al., 1972).
