Temporal patterning of neural responses to complex sounds are hypothesized to play a critical role in conveying the information in speech, music, and environmental sounds, both in quiet and especially in noisy backgrounds. These patterns include both the representation of temporal fine structure and the slower fluctuations associated with the envelopes of complex sounds. This workshop will comprise a series of presentations that provide state-of-the-art information about the origins of temporal patterning in the auditory periphery and transformations of these patterns along the ascending neural pathways. We will also hear about implications of temporal patterning of neural responses for understanding animal behavior and human psychophysical performance, for listeners with normal hearing and hearing loss. Finally, recent applications of ideas concerning temporal patterning to speech processing and hearing-aid strategies will be presented.
One goal of this workshop is to provide a forum for discussion of cutting-edge research related to temporal representations, bringing together researchers from a wide range of auditory laboratories. Another goal is to provide, for graduate students and post-doctoral trainees, a focused overview of recent findings related to auditory temporal responses and related signal processing. In addition to the invited lectures outlined below, students and post-docs will have an opportunity to receive feedback on their ongoing work during poster presentations.

Specific topics will include:

  1. Effects of cochlear tuning and nonlinear mechanical, transduction, and neural mechanisms on the representation of sounds in low-frequency neural fluctuations, at many levels of the auditory pathway.
  2. Influence of phase/fine structure on neural fluctuations – e.g. interactions between fine structure and envelopes, resulting in the low-frequency fluctuations that drive CNS neurons that are sensitive to periodicity.
  3. Implications of the properties of neural fluctuations for understanding behavioral/psychophysical sensitivity, and efferent control of the periphery by the CNS.
  4. Applications to speech processing, especially for listeners with hearing loss.
