Article title: Age-related changes in sound onset and offset intensity coding in auditory cortical fields A1 and CL of rhesus macaques

Authors: Deepa L. Ramamurthy and Gregg H. Recanzone

From the authors: “Neural responses to sound onset and offset were affected to different extents, and their rate-level functions became more mutually similar, which could be accounted for by the loss of nonmonotonic intensity coding in geriatric monkeys. These findings were consistent with weakened inhibition in the central auditory system and could contribute to auditory processing deficits in elderly subjects.” 

This study is highlighted as one of April's "best of the best" as part of the American Physiological Society's APSselect program.
