For more than a century, the story of the brain has been told as a tale of neurons, with every thought and memory traced to their electrical chatter. That narrative is now being rewritten as evidence ...

New experiments reveal how astrocytes tune neuronal activity to modulate our mental and emotional states. The results suggest ...

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.

A collaborative French-Swiss study reveals a previously unknown role for astrocytes in the brain's information processing. Published in the journal Cell, the research shows that these glial cells are ...

Astrocytes are notoriously two-faced—calmly coddling neurons one minute, then ruthlessly consuming their synapses the next. Why these dramatic mood swings? Blame the EphA4 receptor, according to a ...

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 the nervous system.

Major depressive disorder (MDD) is a mental health condition that negatively affects the mood of a person and causes a loss of interest in activities that were previously associated with happiness. In ...
