Between the axon of a transmitting neuron and the dendrite of a receiving neuron is a gap called the synapse—the site at which signals are passed between the brain cells. The nervous system ...

The claim is intriguing, but it’s too soon to redraw axons, says Pramod Pullarkat, a physicist who studies neuron structure ... the experiments with a type of axon that isn’t wrapped in ...

Neurotransmitters are tiny chemical messengers that carry, boost, and balance signals between neurons (aka nerve cells) and ...

Axon guidance is the pathfinding step that enables axons—the longest part of a neuron, through which the nerve impulse is propagated outside the cell—to be correctly directed to their target.

Here, an axon from one neuron links to a dendrite of another. At these synapses, neurotransmitters carry signals across the ...

Furthermore, experiments with the mathematical model and mouse brain samples showed that increasing the concentration of sugars in the solution around the axon or decreasing tension in the axonal ...

The work took advantage of a type of microscopy that better preserves neuron structure. In three types of mouse neurons—some grown in petri dishes, others from adult mice and mouse embryos—the team ...

They discovered in human stem cell models of MND, the axon - the long part of the motor neuron cell that connects to the muscle - was shorter than in healthy cells. And the movement of the ...
