Mouse auditory perception of temporal features of sound

The house mouse has developed into a promising model in hearing research, allowing for the integration of behavioral (psychoacoustic) and physiological data from the same species. The present dissertation focusses on psychoacoustics and investigates two aspects of temporal processing in the mouse, a) the ability to discriminate signals of different duration (duration discrimination), and b) the ability to exploit correlated amplitude fluctuations in a noise masker to enhance signal detection (comodulation masking release, CMR). The results of the duration discrimination experiments are compared with the results of physiological recordings in the mouse (Brand et al. 2000), and the most likely mechanisms to explain the findings are discussed. Likewise, the results of the CMR experiment are used to infer the mechanisms playing a role in the processing of temporally structured signals in the hearing system.
