As for astrocytes, three subsets emerged. One expressed high levels of EphA4 along with genes involved in astrocyte reactivity, phagocytosis, and synapse elimination. The latter included the ...

Astrocytes, star-shaped glial cells in the brain, form specialized networks active during reward-driven behaviors. Using a tool called AstroLight, ...

“When you’re startled or overwhelmed, there’s so much activity going on in your brain that you can’t take in any more information,” said Kira Poskanzer, PhD, an associate professor of biochemistry and ...

Astrocyte cells–not just neurons–could be key in processing memories. Get the Popular Science daily newsletter💡 Breakthroughs, discoveries, and DIY tips sent every weekday.

Serotonin triggers changes in astrocyte gene expression patterns, turning astrocytes into a hub of olfactory sensation processing,” Sardar said. “This project has uncovered novel aspects of astrocyte ...

A lesser-known type is the astrocyte, a somewhat star-shaped cell that secretes proteins critical for proper brain development. Astrocytes “tell the neurons what to do,” says Nicola Allen, ...

Overlooked contributions from astrocytes might explain the human brain's huge storage capacity. Story by Anne Trafton • 5h. T he human brain contains about 86 billion neurons.

Little-known cells might be key to human brain’s massive memory. A new model suggests that astrocytes might be used in computation, coordinating with neurons and connecting synapses in networks.

Astrocyte cells critical for learning skilled movements Date: March 10, 2023 Source: Picower Institute at MIT Summary: When astrocyte function is disrupted, neurons in the brain's motor cortex ...

"It is known that astrocytes are a heterogeneous cell type in their molecular and gene expression signatures, morphology and origin," Marta Navarrete, senior author of the paper, told Medical Xpress.
