title: [The discrimination of frequency-modulated signals under free behavior conditions in cats].
abstract: Cats were trained to discriminate stimuli linearly modulated in frequency. Discrimination threshold were measured with limit method. The differential threshold, delta F/F0.100%, turned out to be constant and equal to be about 3% in the range of 1.5-6.5 kHz with no dependence on both temporal structure and frequency variation rate.
