A new study reveals that astrocytes, once dismissed as mere support cells, play a central role in fear memory.

Picture a star-shaped cell in the brain, stretching its spindly arms out to cradle the neurons around it. That's an astrocyte, and for a long time, scientists thought its job was caretaking the brain, ...

To better model how neurons fire and interact with glia, some scientists place the cells into a brain or grow them in an organoid. Others have produced little spheres of human neural tissue by ...

In the brain, synaptic plasticity - the ability to change neuronal connections over time - is fundamental to learning and memory. Traditionally, science has focused on nerve cells and their synapses.

The potential effects of astrocyte dysfunction in neurodegenerative diseases are summarized in Figure 2. AD is characterized clinically by cognitive loss in two or more domains, including memory, ...

A study by researchers at Baylor College of Medicine may change the way we understand memory. Until now, memories have been explained by the activity of neurons that respond to learning events and ...

A study published in Nature by researchers at Baylor College of Medicine changes the way we understand memory. Until now, memories have been explained by the activity of brain cells called neurons ...

CAMBRIDGE, MA -- The human brain contains about 86 billion neurons. These cells fire electrical signals that help the brain store memories and send information and commands throughout the brain and ...

A new study changes the way we understand memory. Until now, memories have been explained by the activity of brain cells called neurons that respond to learning events and control memory recall.
