MIT scientists find rotating brain waves help the mind refocus after distraction

Researchers at MIT’s Picower Institute report that rotating waves of neural activity help the brain recover focus after distraction. In animal studies, the extent of these rotations tracked performance: full rotations aligned with correct responses, while incomplete cycles were linked to errors. The timing between a distraction and response also mattered, suggesting a timing‑dependent recovery cycle.
Researchers at MIT have mapped a previously underappreciated brain circuit that alters how visual information is processed depending on an animal’s level of arousal and movement. In a study in mice, they show that the prefrontal cortex sends specialized feedback signals to visual and motor regions, tightening or loosening visual representations according to behavioral state, as reported in Neuron.

A recent MIT study suggests that artificial intelligence could currently displace up to 12% of the total US jobs market. This equates to one in nine workers potentially affected. The findings highlight ongoing concerns about AI's impact on employment.
