In a study published in Neuron, Ciaran Murphy-Royal, researcher at the Center de recherche du Center hospitalier de l'Université de Montréal (CRCHUM), and his team show that astrocyte activity in the ...

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 ...

Astrocytes, once thought to be mere brain “support cells,” are now revealed to be key players in fear memory. Researchers found they actively help form, recall, and weaken fear responses by ...

Once overlooked, astrocytes are increasingly recognized as star players in Alzheimer’s disease, with recent studies blaming them for feeding into a neurotoxic stew that kills neurons. In the September ...
