Story summary

A Hebrew University of Jerusalem study, led by Prof. Israel Nelken, shows the auditory cortex operates differently when people focus on tasks.
During engagement, the brain synchronizes to the task rhythm, boosting sound processing.
Instead of merely reacting, the cortex predicts and prepares for expected sounds, acting as an adaptive filter.
The mechanism could improve hearing aids and attention training by helping people stay focused in noisy environments.
