Neurodegenerative disease profoundly affects structures and pathways responsible for memory, cognition, and higher-order ...

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 ...

(Nanowerk News) Researchers have developed a laser-based artificial neuron that fully emulates the functions, dynamics and information processing of a biological graded neuron. With a signal ...

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 ...

In a study published in Cell on July 10, researchers reported the first comprehensive study of whole-brain projectomes of the macaque prefrontal cortex (PFC) at the single-neuron level and revealed ...

New research suggests that super-agers generate twice as many neurons as typical older adults. But you don't have to be a ...

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 ...

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, ...

While the exact causes of neurodegenerative brain diseases like Alzheimer's and dementia are still largely unknown, researchers have been able to identify a key characteristic in affected brains: ...

Researchers developed a chip-based quantum-dot laser that emulates a biological graded neuron while achieving a signal processing speed of 10 GBaud. WASHINGTON — Researchers have developed a ...
