Psychological and Physiological Acoustics Session 3aPP: Auditory Physiology and Modeling (Poster Session) 3aPP15. A computational model of spatial tuning in the auditory cortex in response to competing sound sources

Single neurons in the auditory midbrain are sharply tuned to preferred directions, while cortical neurons show broader tuning. (King et al, 2007) Recent experiments on cortical responses in birds revealed the emergence of spatial tuning to multiple competing sounds in the cortex. (Maddox et al, 2012) In this situation cortical neurons show broad tuning to single-location stimuli, but develop sh...

Effects of spontaneous otoacoustic emissions on frequency discrimination

Enhancing mammalian hearing by a balancing between spontaneous otoacoustic emissions and spatial coupling

Nonlinear dynamics has provided significant insights into the origin of frequency discrimination and signal amplification underlying mammalian hearing. Existing signal amplification models, however, tend to ignore two basic known aspects of the hearing: spontaneous otoacoustic emissions (SOAEs) and intrinsic dynamical coupling in the cochlea. We construct and study a class of coupled-oscillator...
