AB  - The brain's cerebral cortex decomposes visual images into information
      about oriented edges, direction and velocity information, and color.
      How does the cortex decompose perceived sounds? A reverse correlation
      technique demonstrates that neurons in the primary auditory cortex of
      the awake primate have complex patterns of sound-feature selectivity
      that indicate sensitivity to stimulus edges in frequency or in time,
      stimulus transitions in frequency or intensity, and feature
      conjunctions. This allows the creation of classes of stimuli matched to
      the processing characteristics of auditory cortical neurons. Stimuli
      designed for a particular neuron's preferred feature pattern can drive
      that neuron with higher sustained firing rates than have typically been
      recorded with simple stimuli. These data suggest that the cortex
      decomposes an auditory scene into component parts using a feature-
      processing system reminiscent of that used for the cortical
      decomposition of visual images.
