Age-related memory decline and neurodegenerative diseases like Alzheimer's are often thought of as irreversible. But the brain is not static; neurons continually adjust the strength of their ...

To think, feel, talk and move, neurons send messages through electrical signals in the brain and spinal cord. This intricate communication network is built of billions of neurons connected by synapses ...

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 ...

Neurons from grafted stem cells contain intrinsic codes for navigating and forming connections, which may improve cell therapy for a brain short-circuited by stroke. Some parts of our bodies bounce ...

Let us begin the new year with a renewed commitment to protecting our brain health. We often hear that the mind and body are connected—and this is absolutely true. Brain health is body health.

Motor neurons are some of the largest cells in the human body. In particular, upper neurons—extending from the cerebral cortex to the brain stem or spinal cord—average 60μm in diameter. 3,4 These ...

“Illusions are fun, but they are also a gateway to perception,” says Hyeyoung Shin, assistant professor of neuroscience at Seoul National University. Shin is the first author of a new study in Nature ...

For decades, scientists have tried to build electronics that behave like the brain. The idea is called neuromorphic computing in which chips are designed to copy the way our brain’s neurons fire and ...

From Santiago Ramón y Cajal’s hand came branches and whorls, spines and webs. Now-famous drawings by the neuroanatomist in the late 19th and early 20th centuries showed, for the first time, the ...

An artificial neuron made of conductive plastics that can perform advanced functions similar to those of biological nerve cells has been demonstrated by researchers at Linköping University, Sweden.

Pediatricians and parents — and, really, anyone who works with children — have long known that a child’s social needs evolve with age. Yale researchers have now discovered the neurological signaling ...

A new Yale study has revealed that neurons — the energy-hungry cells that connect and direct activity in the brain — are equipped with “backup batteries” that kick in to keep the brain running during ...
