Researchers at Tulane University, with a team of colleagues from eight other universities, have discovered a new nerve cell signaling mechanism that could transform our understanding of pain and lead ...

New experiments reveal how astrocytes tune neuronal activity to modulate our mental and emotional states. The results suggest that neuron-only brain models, such as connectomes, leave out a crucial ...

Researchers have a new hypothesis for how brain cells called astrocytes might contribute to memory storage in the brain. Their model, known as dense associative memory, would help explain the brain's ...

Regular activity not only strengthens muscles but can bolster our bones, blood vessels, and immune system. MIT engineers have now found that exercise can also have benefits at the level of individual ...

Neurons talk to one another using electricity. If you could hear these impulses, they might sound like constant, rapid-fire chatter all over the nervous system. Heart muscle cells do something similar ...

New research has shown that Sonic Hedgehog (SHH)–Gli1 signaling in microglia amplifies inflammatory responses through the IKKβ/NF-κB pathway, contributing to dopaminergic neuron loss in Parkinson’s ...
