#Astrocytes

Scientists have discovered a way to help the brain clean itself of harmful Alzheimer’s plaques by activating its own support cells. By increasing a protein called Sox9, researchers were able to boost the activity of astrocytes, star shaped cells that help…

From Reddit - r/science: Astrocytes in the basolateral amygdala are found to contribute to fear memory retrieval and extinction in mice, with calcium signaling in astrocytes supporting neuronal representations associated with learned fear responses

Webs of star-shaped cells called astrocytes connect distant parts of the brain, allowing long-distance exchange of molecules. Webs of star-shaped cells called astrocytes connect distant parts of the brain, allowing long-distance exchange of molecules.

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 interacting with neurons in real time.…
