(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).
Pain messages travel along the peripheral nervous system until they reach the spinal cord. The gate control theory proposes that there are gates on the bundle of nerve fibers in the spinal cord between the peripheral nerves and the brain.These spinal nerve gates control the flow of pain messages from the peripheral nerves to the brain.ain messages may also be directed along a variety of pathways in the brain. 1  For instance, a fast pain message (A-delta fiber) is relayed by the spinal cord to specific locations in the brain, namely the thalamus and cerebral cortex.
