Cientistas acham o “filtro de foco” escondido no cérebro

We live with many notifications. They make it hard to focus. Now scientists found something new in the brain. It is a small group of brain cells. They sit deep in an old part of the brain. These cells work like a filter. They push away distractions. They help you look at what is important. Scientists tested this in mice. They turned the cells off. Then the mice could not focus well. Later they turned the cells back on. And the mice could focus again. This part of the brain is very old. Fish and birds have it too. One day, this may help people. It may bring better medicine for problems with focus.
