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 ...

Researchers find that the amygdala is a sophisticated mediator that chooses between action-based and stimulus-based learning ...

Add Yahoo as a preferred source to see more of our stories on Google. Mice moving tiny steering wheels to control shapes on a screen have given scientists an unprecedented view of how decisions unfold ...

Decisions run our lives. From the moment we wake up and decide to get out of bed to the moment we turn off the light and decide to sleep, we make decisions. Those who can make hard decisions are ...

Visualization of 75,000 neurons (colored dots) active across the brain of an adult mouse across different stages of a decision-making task. Dot size reflects a cell’s average firing rate, such that ...

The walk sign lights up, and you’re ready to step off the curb when you hear the blare of an ambulance siren—or the sound of kids screaming, or even some leaves rustling in the wind. How do you make a ...

To better understand decision-making, researchers can create computational models—groups of equations that aim to predict what decisions people would make when faced with a set of choices. For example ...

Every decision begins invisibly. Long before someone acts, the brain is already hard at work gathering evidence, weighing options, and gradually committing to a choice. But even when faced with the ...

The brain favors repeating past actions over rational choice, explaining why we stick to habits even when better options exist.

For the first time, scientists have mapped how nearly an entire mammalian brain lights up as decisions are made. The massive effort, which tracked single neurons across almost the whole mouse brain, ...
