Description
Simon Dobri, Jean Chen, and Bernhard Ross present a 2023 study of how the brain's 40 hertz rhythm changes with age and hearing. The rhythm helps the brain bind sound features together, and it is steered by a calming chemical messenger. That messenger fades with age, which may loosen the rhythm and hurt speech hearing in noise.
The team recorded brain magnetic fields in young and older adults as they heard modulated tones, in quiet and in babble noise. Responses in quiet came later and larger in the older group. The study ties rhythm strength to hearing scores and to levels of the calming chemical in the hearing cortex.
