Neuroscientists closer to understanding how circuits in the brain’s “hearing center” spur responses

Research supported in part by the Swartz Foundation

Cold Spring Harbor, N.Y. – Just as we visually map a room by spatially identifying the objects in it, we map our aural world based on the frequencies of sounds. The neurons within the brain’s “hearing center”—the auditory cortex—are organized into modules that each respond to sounds within a specific frequency band. But how responses actually emanate from this complex network of neurons is still a mystery.

A team of scientists led by Anthony Zador, M.D., Ph.D., Professor and Chair of the Neuroscience program at Cold Spring Harbor Laboratory (CSHL) has come a step closer to unraveling this puzzle. The scientists probed how the functional connectivity among the neurons within the auditory cortex gives rise to a “map” of acoustic space. “What we learned from this approach has put us in a position to investigate and understand how sound responsiveness arises from the underlying circuitry of the auditory cortex,” says Zador. His team’s findings appear online on October 17th in Nature Neuroscience.
