We are interested in basic aspects of hearing, from perception to receptor physiology. We explore mechanisms underlying sound detection and discrimination. We are also interested in developing suitable measures of accuracy and precision for discrimination and matching tasks, because existing textbook measures often fail to separate the concepts of accuracy and precision, such as when stimulus parameters can attain only positive real values. These insights have widespread implications for many fields.
We also analyze the timing of auditory-nerve-fiber spikes, the first possible precursors of the ‘sensory events’ involved in perceptual detection and discrimination. We developed the first model to account for all major aspects of spike timing in mammalian ANFs during spontaneous activity. The model will help better understand spike timing during sound-driven activity, including phase locking.
