(July 2014) In computer science, in particular networking, a session is a semi-permanent interactive information interchange, also known as a dialogue, a conversation or a meeting, between two or more communicating devices, or between a computer and user (see Login session).
Spinal Cord and Peripheral Nerve Stimulation. Signals generated through the spinal cord and peripheral nerves in the form of nerve impulses are the information pathways that the brain learns about the environment and reacts to the stimulation (using muscle contraction such as the withdrawal reflex).
The peripheral nerves are a complicated, extensive network of nerves that are the tool for the brain and spinal cord to communicate with the rest of the body. They are fragile and can be damaged easily. When one of these nerves suffers injury or trauma, surgical treatment is sometimes the only remedy.
