- Neuroscientists mapped the entire brain activity of mice during decision-making for the first time.
- The study involved recording activity from over 620,000 neurons across 279 brain regions in 139 mice.
- Decision-making was found to be a coordinated process across multiple brain areas, not localized to a single region.
- Mice were trained to turn a steering wheel for rewards, with their brain activity monitored during the task.
- The neural map produced has unprecedented resolution, covering 95% of the rodents' brain volume.
- Results were published in 'Nature', with the dataset made publicly available for further research.
- The study supports the idea that more brain areas are involved in decision-making than previously thought.
- The human brain contains ~86 billion neurons, consumes 20% of the body's energy, and remains unmatched in efficiency by computers.
- This research is a step toward understanding human decision-making processes.
