Scientists created new tools to study brain messenger proteins called neuropeptides in the brains of behaving animals, discovering they are the primary messengers in the fear circuit in mouse brains, ...

Columbia University researchers have discovered how variants of the ABCA7 gene, which are common among Black Americans, increase the risk for Alzheimer's disease. The paper is published in the journal ...

Neuropeptides play fundamental roles in modulating cellular and circuit functions within the brain. One such signaling molecule -- orexin -- regulates arousal and wakefulness, and its failure can lead ...

In the split second as you accidentally touch the hot handle of a cast iron skillet, pain and a sense of danger rush in. Sensory signals travel from the pain receptors in your finger, up through your ...

Cerebral ischaemia, marked by a sudden reduction in blood flow, triggers a cascade of molecular events leading to neuronal injury. Neuropeptides have emerged as key modulators in this context, capable ...

Some ants within the colony patrol the neighborhood to protect the nest from intruders, while others stay inside to care for the young. Various molecular mechanisms, from hormone and neuropeptide ...

COVID-19 has put a spotlight on the pulmonary and nervous systems, but there is still much to learn about how they interact. Researchers at University of California San Diego School of Medicine ...

Our human brains can seem like a crowning achievement of evolution, but the roots of that achievement run deep: The modern brain arose from hundreds of millions of years of incremental advances in ...

Salk scientists create methods to study messenger proteins in the brain called neuropeptides, finding they control the brain’s fear response in mice—a finding that may help develop more effective ...
