A neuron is a nerve cell that is the basic building block of the central nervous system and peripheral nervous system. Neurons are similar to other cells in the human body in a number of ways, but ...

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 ...

Living neurons receive signals from different sources, process them and pass an output signal on to other neurons (left). In the artificial neuron model, this information processing can be described ...

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 ...

There's no doubt that exercise does a body good. Regular activity not only strengthens muscles but can bolster our bones, blood vessels, and immune system. Now, MIT engineers have found that exercise ...

Neuroscientists have long dreamed of watching thoughts unfold as they happen, without disturbing the fragile tissue that produces them. That vision is suddenly closer to reality, as glowing neurons ...

Most people wouldn’t give Geobacter sulfurreducens a second look. The bacteria was first discovered in a ditch in rural Oklahoma. But the lowly microbe has a superpower. It grows protein nanotubes ...

For decades, neuroscientists have been trying to pinpoint the neural underpinnings of behavior and decision-making. Past studies suggest that specialized groups of neurons in the mammalian brain, ...

A tiny stack of printed nanomaterials, thinner than a human hair and flexible enough to bend with living tissue, just did something no fabricated device has done before: it fired electrical spikes so ...
