IN A FIRST, SCIENTISTS MAP COMPLETE BRAIN ACTIVITY DURING DECISION-MAKING

Summary from the TLDR newsletter

Researchers have mapped decision-making at a single-cell resolution across an entire mouse brain. The effort by the International Brain Laboratory, a global consortium of 22 labs, was coordinated by three Princeton labs. The experimental setup involved making mice move tiny steering wheels to control shapes on a screen while recording neural activity using high-density electrodes. The work showed that decision-making is very broadly distributed throughout the brain, including in regions previously thought not to be involved. The coordination of 22 labs worldwide demonstrates the power of large-scale neuroscience.
