(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).
Although the brain is the control center, its job would not be possible without the spinal cord, which is the major conduit for information traveling between brain and body. Peripheral system nerves branch from either the brain stem or the spinal cord.
