Medically reviewed by Nicholas R. Metrus, MD Key Takeaways Neurons are cells that transmit electrical signals through the nervous system.Motor neurons control muscle activity and movement by carrying ...

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 processing speed of 10 ...

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 are the specialized cells that allow our bodies to transmit impulses, like factories that process inputs. They send signals that help us catch a ball, recognize a favorite song or pull our ...

Scientists have uncovered how a newly discovered gene, NEK1, in which mutations have been linked to ALS cases, disrupts the function of the motor neuron and causes it to degenerate and die. The viral ...

Our mushy brains seem a far cry from the solid silicon chips in computer processors, but scientists have a long history of comparing the two. As Alan Turing put it in 1952: “We are not interested in ...

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 ...
