(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).
Organization of the Peripheral Nervous System. With the exception of the cranial nerves, peripheral nerves all travel to and from the spinal cord. Sensory nerves enter the spine near the back of the spinal cord, and motor fibers exit from the front of the cord.
