Single unit activity was recorded in the striate cortex of vision-deprived cats aged between 3 and 8 weeks. Contrast sensitivity or response measurements made using moving sinusoidal gratings were used to construct spatial frequency tuning curves. At 3 weeks sensitivity, selectivity (assessed both a
Responses of simple and complex cells in cat striate cortex were studied with moving sine-wave gratings before and during application of the GABAA receptor antagonist bicuculline methiodide. Both simple and complex cells exhibited a broadening of their spatial frequency tuning functions under bicucu
