First complete map of mouse brain activity reveals intuition clues
Scientists mapped a mouse brain during decision-making, revealing insights into intuition.
Why it matters
- First complete activity map of a mammalian brain during complex behavior.
- Reveals how decisions are made and may explain intuition.
By the numbers
- Over 650,000 neurons studied.
- 12 labs collaborated on the research.
- Mice used a Lego steering wheel to move a target on a screen.
The big picture
- Decision-making involves multiple brain areas working together.
- Decision-related signals build up before action, hinting at intuition.
- Findings suggest decisions may be influenced by prior knowledge unconsciously.
What they're saying
- Some commenters are concerned about the implications of predetermined decisions.
- Others reflect on the ethical treatment of animals in research.
Caveats
- The link to intuition is speculative.
- Study conducted in mice, not humans.
What’s next
- Researchers aim to apply findings to understand conditions like autism.
