When surgeons dissect tissue to remove a tumor or make a repair, they must work cautiously, relying on electrophysical ...

To the point Nerve cells in the hypothalamus: These neurons influence eating behavior and weight gain. Hormone-controlled: These nerve cells are controlled by the hormone leptin, which suppresses ...

Remyelination is the process by which myelin, the fatty substance surrounding nerve cells that’s lost in multiple sclerosis (MS), is restored; it’s the goal of CNM-Au8 treatment, which aims to ...

The body contains various types of nerve cells, including graded neurons that encode information through continuous changes in membrane potential, allowing subtle and precise signal processing. In ...

Laser-based artificial neuron mimics nerve cell functions at lightning speed With a processing speed a billion times faster than nature, chip-based laser neuron could help advance AI tasks such as ...

Earlier versions injected the cells at the site of the injury, but the Phase I/IIa trial will use 1-2 cm (0.4-0.8 inch) bridges built of millions of olfactory ensheathing nerve cells.

Multiple Sclerosis Multiple sclerosis (MS) is the most common disease associated with myelin damage, immune cells attack myelin—and eventually, the axons—in the brain and spinal cord. Repeated attacks ...

This, in turn, can trigger action potential impulses that rapidly propagate up the afferent nerve toward the brain. “Protons have never been previously reported as principal transmitters in any ...

The process starts when a signal, also called an action potential, is sent from the neuron's cell body towards the axon. Along the surface of the axon membrane are channels that allow ions like sodium ...

But how do brain cells send messages? The first step in this messaging process is the action potential, or a wave of electricity triggered in the nerve cell, or neuron.

Because they are Neurons, sometimes called nerve cells, make up around 10 percent of the brain; the rest consists of glial cells and astrocytes that support and nourish neurons.
