The efferent nerves, like the name applies, are effector nerves of the peripheral nervous system. This class of nerve covers everything that runs from the brain, to the body, controlling responses in muscle and other tissue.

Stimulation of the vagus nerve is one usage that we already have for neurostimulators. The vagus nerve is one of the most critical body sensory and control nerves since it does not deal with the outer body, instead heading straight down into the organs of the torso.
This article is intended to serve as a general introduction to the nerve layout in the human arm and hand. It is not concerned with bone or muscle layout, but simply with the areas affected by each nerve pathway, and data type. It exists as an aid to those desiring to create a replacement arm, either prosthetic or virtual, and understand purely which area of the limb feeds sensory information to which part of the nervous system.
A new method of integrating electrodes and neurons into a single device, offers some tempting possibilities for new neuroprosthetics, and nerve-operated prosthetics in general.
We finally understand enough about the way sound signals are processed into electrical signals, to go one better than the cochlea implant. We can tap directly into the auditory nerve itself.
A quote from the book Profiles of the Future, by Arthur C Clarke on the creation of artificial eyes by decoding the optic nerve, is compared to more recent advances doing just that.
Discussion of a possible hardware-based neuroprosthetic interface method designed to maximise speed gain in body-machine sensory interfaces.
The 'virtual light' class of retinal displays, are perhaps unique in the display industry, because they don't actually display anything. The entire concept is built round bypassing the eye entirely, and dropping visual encoded information directly into the optic nerve.
Haptics is the study of the sense of touch. There are many parts to touch, and five different types of touch nerve in the nervous system. Here, we look at what goes into detecting texture, how the nerves work, and some initial attempts to interface with them for VR.
A news story from April 2008. An engineered material that can be injected in fluid form into damaged spinal cords could help prevent scars and encourage damaged nerve fibres to regrow along a scaffold it provides as it solidifies.
Its early 2009, and the University of Southampton, in the UK, is developing electrical stimulation technology, designed to help stroke patients relearn movement, by duplicating the natural, original nerve impulses. The technology is a direct offshoot of work to decode the electrical signals of the peripheral nervous system.
