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.
