Researchers at the University of Michigan have discovered that the constant gnawing of rodents isn't just a reflex or a consequence of a tough diet. It also triggers a release of dopamine in the brain ...

The drugs have names that sound like small planets: semaglutide, liraglutide, lixisenatide. Collectively, they belong to a class of glucagon-like peptide 1 (GLP-1) analogs that has reshaped the ...

Researchers map the peptide behind semaglutide across 25 brain regions in each sex, finding striking differences in ...

Expecting sugar increases the brain's reward response to artificial sweeteners, suggesting labels like "diet" may sabotage ...

A new study shows how dysfunctional packaging of the neurotransmitter dopamine triggers toxic processes in neurons—and how ...

Summary: Blockbuster weight-loss drugs like semaglutide (Wegovy/Ozempic) and liraglutide (Saxenda) have transformed metabolic health, but we are only just beginning to understand where they work in ...

Here's how the amygdala processes fear and why it plays a key role in phobias. This is how the brain detects threats and triggers emotional fear responses.

Human pluripotent stem-cells (HPSCs)—including human embryonic stem-cells and human induced pluripotent stem-cells—are reshaping the landscape of regenerative medicine.1,2 In Parkinson's disease, ...

The finding reveals a previously hidden motivation for gnawing in mammals, which could help lead to more effective treatments for oral health issues in humans Study: A Touch-Guided Neural Circuit ...

In a new study from Karolinska Institutet, published in Nature Neuroscience, researchers have identified the neurogenic progenitor that gives rise to dopaminergic neurons, the primary neurons affected ...

A new study shows how dysfunctional packaging of the neurotransmitter dopamine triggers toxic processes in neurons – and how this can be repaired with simple delivery of energy (ATP).
