Abstract

The dynamics of the response patterns of the mouse auditory midbrain single neurons in the whole neuronal excitatory receptive field was studied by the extracellular recordings of the pulse activity of neurons. The obtained data showed that the V-shaped neurons demonstrated the highest stability of their responses among the whole population of ICC neurons. The discharges of both primary-like and inhibition-dominated neurons were more variable and their variations more likely followed the changes of the sound frequency and intensity. Changes of the discharge pattern of the vast majority of studied neurons occurred 1/3–1/2 octave away the neuronal CF in the direction of both the low-frequency and high-frequency borders of the neural FRA. The results of present study are discussed taking into account the available data about the formation of IC neurons response due the interaction of the excitatory and inhibitory processes mediated by the activation of different types of cellular glutamate and GABA receptors.
