Neural signatures commonly observed when humans make choices can also reflect choice-independent processes
Past neuroscience research has identified patterns in neural activity typically observed when humans are engaged in value-based decision-making. This is the process through which humans choose between options that could be ...

A recurrent neural network-based framework to non-linearly model behaviorally relevant neural dynamics
A key objective of several neuroscience studies is to understand and model how the dynamics of distinct populations of neurons give rise to specific human and animal behaviors. Many existing methods for exploring the link ...

Dietary fat alone does not cause changes in the hypothalamus, mouse study finds
A high-fat diet can promote overweight and increase the risk of metabolic diseases, such as diabetes. In mice brains, this leads to measurable changes in the region of the hypothalamus. However, fat alone does not appear ...

Creating the largest, most comprehensive picture of neural connections to date
Flip a switch on the wall, and it turns on a light across the room through a simple circuit. Now add 140,000 other switches and try and figure out which one controls the light. That is similar to the challenge undertaken ...

Brain scan study shows what happens in the brain when a person with schizophrenia hears voices
Auditory hallucinations are likely the result of abnormalities in two brain processes: a "broken" corollary discharge that fails to suppress self-generated sounds, and a "noisy" efference copy that makes the brain hear these ...

Our brains divide the day into chapters: Psychology research offers details on how
The moment a person steps off the street and into a restaurant—to take just one example—the brain mentally starts a new "chapter" of the day, a change that causes a big shift in brain activity. Shifts like this happen ...

Turning brain cells on using the power of light: Researchers refine noninvasive method of bioluminescent optogenetics
University of Rochester researchers have demonstrated a noninvasive method using BL-OG, or bioluminescent optogenetics, that harnesses light to activate neurons in the brain. The ability to regulate brain activation could ...
