Estimation of acoustic stimuli features in the brainstem. A network model

A model is proposed to explain perception of binaural (received at the two ears) stimuli with different interaural onset time and intensity. The acoustic signals are transformed by the ears into stochastic series and the features of these series are compared in a multi-level system. In each level the interaural differences are estimated. The model is based on physiological and anatomical data and also quantitatively accounts for both physiological and psychoacoustical experimental results for healthy subjects and patients
