Ripples in the Anterior Auditory Field and Inferior Colliculus of the Ferret

Abstract

Stationary and traveling ripples can be used to extract spectral and temporal properties of auditory cortical neurons. Linearity: Responses to a broad-band complex stimuli, decomposed into a linear combination of ripples, can be predicted by summing the neuronal responses to the individual ripples. Only Cortical neurons are selective to ripple frequencies; Collicular neurons are low-pass with respect to ripple frequencies. Therefore, AI and AAF neurons could perform a multi-scale analysis of spectral shape: the spectral profile is analyzed at different degrees of resolution by neurons with receptive fields of different best frequencies, bandwidths and asymmetries.
