Axon
The long cable that carries your brain's electrical signals from one cell to the next — your neural wiring.
The long, thin fibre extending from a neuron that carries electrical signals away from the cell body to the next neuron. Like a cable connecting two devices. Some axons are very short; others can be over a metre long (reaching from the spine to the toes). The speed of signal transmission depends on whether the axon is wrapped in myelin insulation.
How it works
Your axon is the output fibre of a neuron, carrying electrical signals away from the cell body. Some axons are insulated with myelin for speed. Bundles of axons form the brain's 'white matter' — the information highways connecting regions.
Think of it like
It's like the cable connecting your router to your computer — the signal travels along it from source to destination.
What it feels like
You won't feel individual axons, but the speed of your reactions and the clarity of your thoughts depend on how well they're working.
