Central Nervous System The Central Nervous System or CNS is the brain itself, as opposed to the Peripheral Nervous System or PNS. It refers to everything from the brainstem up. Adjusting, or interfacing with the CNS is the most difficult route available in sensory interfacing, but also the most potentially rewarding in terms of complete immersion in a VR. Below, we offer a selection of links from our resource databases which may match this term.

Unlike in the peripheral nervous system, where cells are often unable to distinguish which branching pathway an electrical system is travelling from, the central nervous system makes use of sophisticated internal networks not too dissimilar from an IP record, to differentiate between nervous pathways.
Gila cells are more or less an unknown quantity in the nervous system. In humans and other mammals, in insects, in brds; in practically all lifeforms with a brain, gila cells exist, in the central nervous system and the periphery, binding the neurons together.
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.
The diagrammatic representation for easy understanding, of how dendrites and axons in the nervous system might be attached to a a remote body via the Internet.
The temperature problem is a major issue for actual prosthetics. Not being at all aware when your arm is on fire, is a very bad - and potentially expensive - possibility for any user of a modern prosthetic, even one tied into the nervous system.
There are twelve cranial nerve pairings (making 24 nerves in total) which split out from the brain, and move to cover the needs of the cranium and face, rather than make their way down through the central spinal cord. These nerves are important to consider, as most are of critical importance to sensory data, yet do not pass through the central cord, and so cannot be intercepted at the same juncture. One of the severe problems with haptic input devices (other than the very, very basic type that jack directly into the nervous system) is that the mechanics of hand-held systems only bend or push so far, then they hit engineered limits and the feeling dissipates.
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 larynx or voicebox is a complex piece of kit to control. Creating an interface for a fully functional artificial one may be beyond us - unless we jack it straight into the brain, and let the nervous system control the new, just the same as the old.Our perception of the world is driven by sensory input which is sent to our brains through sequences of spikes carried by sensory neurons, an incoming/outgoing "language of the brain". This book explores the way in which the nervous system represents or encodes these sensory signals.
