First brain-wide map of decision-making charted in mice

Map of 600,000 brain cells rewrites the textbook on how the brain makes decisions

A new study shows that the brain activity behind decision-making is far more widespread across the organ than first thought.

First map of mammal brain activity may have shown intuition in action

Scientists have mapped the activity that takes place across a mouse's entire brain as it decides how to complete a task - and the results could explain the origin of our gut feelings

First brain-wide map of decision-making charted in mice

Mice turning tiny steering wheels to move shapes on a screen have helped scientists produce the first brain-wide map of decision-making at single-cell resolution in a mammal.

In a First, Brain-Wide Activity Mapped During Decision-Making

A key to understanding the brain lies in unpacking how hundreds of interconnected brain areas process information that leads to various outputs. In order to try to understand this, researchers investigate both single neurons and groups of neurons together. Now, a major advance in this area of neuroscience study has been published: the first complete activity map of the brain has been unveiled by a large international collaboration of neuroscient…

New Brain Map Shows How Decisions Emerge Across the Brain

In a groundbreaking collaboration, scientists created the first complete brain-wide map of decision-making in mammals, charting the activity of more than 600,000 neurons across 279 regions in mice. Using steering wheel tasks and high-density electrode recordings, they found that decision-related signals are far more widely distributed across the brain than previously thought.
