The findings, published in Nature on July 19, shed light on potential neural mechanisms involved in working memory and decision making. "Our study is a step toward thinking of the brain not in terms ...

Researchers found that astrocytes in the amygdala actively encode, maintain, and extinguish fear memories. Altering their ...

When HHMI Investigator Amita Sehgal started studying sleep 25 years ago, the topic elicited a yawn from most biologists. "In ...

We found that new neurons in the adult brain are linked to reduced cognitive decline—particularly in verbal learning, or learning by listening to others. Researchers know that new neurons contribute ...

Can the brain keep working when its architecture changes? Researchers at the University of Geneva (UNIGE) have discovered that neurons located in the wrong place can still carry out their normal ...

An EEG (electroencephalogram) is a painless test that uses small sensors placed on the scalp to measure the brain's ...

Neurons in the bird eye’s inner retina lack a blood supply. Finding how these neurons function without oxygen reveals a role for an enigmatic eye structure. Read the paper: Oxygen-free metabolism in ...

When triggered by an odor, rapid changes in membrane voltage and intracellular calcium ion levels occur in nematode olfactory neurons, causing membrane voltage sensors and calcium ion sensors to ...

When most of us picture the brain, we imagine billions of nerve cells flashing with electrical activity, carrying thoughts, memories and commands from one region to another. Those cells, called ...

New work in fruit flies uncovers an electrical trick that allows neurons to compute direction efficiently by juggling multiple signaling mechanisms. These findings could reframe our understanding of ...

Neurons are the most well-known cells in the brain but they are not the only type of cell in this organ. The other main type is the glial cells, also known as neuroglia. Glia comes from the Greek word ...
