To be able to focus on the world, we need to turn a part of ourselves off for a short while, and this is precisely what our brain does.
They demonstrate more specifically that when we need to concentrate, this network disrupts the activation of other specialized neurones when it is not deactivated enough. The results have just been published in the Journal of Neuroscience.
When we focus on the things around us, certain parts of the brain are activated: this network, well known to neurobiologists, is called the attention network. Other parts of the brain, however, cease their activity at the same time, as if they generally prevented our attention from being focused on the outside world. These parts of the brain form a network that is extensively studied in neurobiology, and commonly known as the "default-mode network", because, for a long time, it was believed that it activated itself when the brain had nothing in particular to do. This interpretation was refined..
