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

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 ...

These in silico models have played a pivotal role in advancing our understanding of how neuronal morphology influences excitability and how specific ion currents contribute to cell function.

Hormone levels fluctuate like the tides, ebbing and flowing according to carefully orchestrated cycles. These hormones not only influence the body, but can cross into the brain and shape the behavior ...

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 ...

An EEG (electroencephalogram) is a painless test that uses small sensors placed on the scalp to measure the brain's electrical activity. It provides a real-time readout of brain "waves"—rhythms ...

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 ...

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 ...

New experiments reveal how astrocytes tune neuronal activity to modulate our mental and emotional states. The results suggest that neuron-only brain models, such as connectomes, leave out a crucial ...

Your brain can still make new neurons when you’re an adult. But how does the rare birth of these new neurons contribute to cognitive function? Researchers know that new neurons contribute to memory ...

The activity of certain neurons may influence our endurance for exercise, and these could be targeted to help us run faster ...
