[Monaural phasic sensitivity of auditory system neurons in the cat].
During monaural stimulation, studies have been made of impulse reactions in neurons from the cochlear nucleus and inferior colluculus to changes in the phase value (psi) of one of the harmonics in two-tone signals. It was shown that about 70% of the neurons from the cochleaur nucleus with a tonic discharge pattern may sharply change their activity (from maximum one up to a complete inhibition) due to changes in psi value. Unlike the cochlear nucleus units, neurons from the inferior colliculus change their tonic or burst-like activity rather seldomly and to a slight extent. At the same time, their phasic on- and especially off-responses exhibit high sensitivity to changes in psi value.
