title: [Frequency following response to cochlear nuclei in cats to polycomponent sonic signals].
abstract: Under chloralose-urethane anaesthesia, by means of spectrograms and dynamic spectrograms studies have been made on frequency following response (FFR) in the cochlear nuclei of cats evoked by sonic stimulation. It was shown that FFR readily reproduces frequencies of the acoustic spectrum of separate tones and two-tonal harmonic complexes (the upper reproduced frequency in FFR - 6.0-6.5 kc/sec). The main deteils of the acoustic spectrum of the sounds of speech are also easily reproduced in FFR. Combination tones were observed in FFR during application of two-tonal harmonic complexes. The first harmonic is inhibited in FFR when combined with higher ones (the fifth or the sixth) or at certain phase angle between the first and the second harmonics ("doubling" phenomenon).
