Pinning down how the brain predicts the consequences of choices

Predicting the outcomes of actions in order to make good decisions is a critical role of brain function. This process is thought to work through two fundamentally different mechanisms called "model-free" and "model-based" ...

How the brain balances emotion and reason

Navigating through life requires balancing emotion and reason, a feat accomplished by the brain region "area 32" of the anterior cingulate cortex. The area maintains emotional equilibrium by relaying information between cognitive ...

Exercise improves memory, boosts blood flow to brain

Scientists have collected plenty of evidence linking exercise to brain health, with some research suggesting fitness may even improve memory. But what happens during exercise to trigger these benefits? New UT Southwestern ...

Brain waves in mice change based on memory age

Researchers have discovered signatures in brain activity that allow them to tell old and new memories apart. A team at Japan's RIKEN Center for Brain Science (CBS) analyzed recordings from mouse brains using a machine-leaning ...

Anterior cingulate cortex

The Anterior cingulate cortex (ACC) is the frontal part of the cingulate cortex, that resembles a "collar" form around the corpus callosum, the fibrous bundle that relays neural signals between the right and left cerebral hemispheres of the brain.

It includes both the ventral and dorsal areas of the cingulate cortex, and appears to play a role in a wide variety of autonomic functions, such as regulating blood pressure and heart rate, as well as rational cognitive functions, such as reward anticipation, decision-making, empathy and emotion.
