Many people do simple actions without thinking about them. For a long time, scientists disagreed about how the brain notices actions. One theory said awareness starts before a movement. Another theory claimed it happens after the movement.
Recently, researchers at Yale University solved this old debate. They studied 67 participants who played a special video game. The team measured brain activity during the game. They found that both theories were correct. The brain uses one signal before the action and another signal after it.
The study also showed that tired people have lower awareness. However, doing routine actions automatically actually helps us in daily life. This research may also help people with brain diseases in the future.

New research shows the human brain anticipates upcoming language by grouping words into grammatical phrases rather than predicting only the next single word. Scientists used brain recordings, behavioral tests and LLM measures across languages.
Dopamine helps lock in new skills during sleep
A study from the University of Michigan finds that dopamine neurons become active during NREM sleep soon after a person learns a movement. Their activity, together with sleep spindles, strengthens motor memories and improves skills after sleep.
