What does decision-making in the brain look like?

Neuroscientists from around the world have worked in parallel to map, for the first time, the entire brain activity of mice while they were making decisions. This achievement involved using electrodes inserted inside the brain to simultaneously record the activity of more than half a million neurons distributed across 95 percent of the rodents’ brain volume.

Thanks to the image obtained, the researchers were able to confirm an already theorized architecture of thought: that there is no single region exclusively in charge of decisionmaking and instead it is a coordinated process among multiple brain areas.

Although the scientists involved acknowledge that the data are not definitive, they represent a starting point in the neural study of decisionmaking. The value of this data lies in the fact that the neural pathway of decisionmaking is now clearer, which will allow scientists to better understand complex thinking abilities and perform more advanced analyses.
