  • Summary

  • In this podcast, author Jian Carlo Nocon (Boston University) discusses the recently published research titled "A robust and compact population code for competing sounds in auditory cortex."

    NEW & NOTEWORTHY

    Little is known about how populations of neurons within cortical circuits encode sensory stimuli in the presence of competing stimuli at other spatial locations. Here, the authors investigate this problem in auditory cortex using a recently proposed information-theoretic approach. They found a small subset of neurons nearly maximizes information about target sounds in the presence of competing maskers, approaching information levels for isolated stimuli, and provides a noise-robust code for sounds in a complex auditory scene.
