Neuron

Neurons were sensory cells in many organisms, including Humans and Bith. They sent information as signals to the brain, where they usually had their highest concentration, and back to other parts of the body, controlling motor and sensory functions.

After breaking the neck of Darth Tenebrous, Darth Plagueis saw microscopically through the Force as the neurons in his master stopped firing and his midi-chlorians died out.

Darth Vader was equipped with a sensor web that attached to his neural system in order to power the prosthetics that he acquired after the Duel on Mustafar. If his neurons failed to send signals to his limbs, he would be rendered immobile and a programmed alert would be automatically sent to the Emperor Palpatine Surgical Reconstruction Center by hyperwave signal.

When Tobb Jadak was in his decades-long coma following a starship collision, his neurons were stimulated at the by Chief Neurologist Lial Sompa at the Aurora Medical Facility. The last time Sompa performed this operation on Jadak was weeks before his awakening in 43 BBY.
