摘要：

Enhancement of auditory transients is well documented in the auditory periphery and mid-brain, and single unit investigations have identified units with responses which may underlie this sensitivity. It is also known that transients are important in psychophysics in, for example, speech comprehension and object recognition and grouping. In this work we use a simple phenomenological model of auditory transient extraction, based on the skewness of the distribution of energy inside a frequency dependent time window, and show that this view is consistent with electrophysiological measurements of auditory brainstem responses. In addition, we present evidence that this representation may provide a positive biological advantage in processing classes of sound that are behaviourlly relevant. (C) 2006 Elsevier Ireland Ltd.
