Adults whose brains still have strong neuron production seem to have better memory and cognitive function than do those in ...

While neurogenesis—the growth of new brain cells—typically slows with age, superagers produce new neurons in the hippocampus at twice the rate of healthy older adults. In contrast, individuals with ...

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 ...

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 ...

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 ...

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 ...

Picture a star-shaped cell in the brain, stretching its spindly arms out to cradle the neurons around it. That's an astrocyte ...

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 ...

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

The enteric nervous system (ENS) is a vast network of nerves built into the walls of the intestine. While it is well known for its role in regulating digestion and the movement of food through the ...

Researchers discover a gut-brain-heart axis where the bacterial metabolite IAA regulates hypocretin neurons to control heart stiffness and blood pressure.
