What
does the NeuroScope actually measure in the body?
The NeuroScope measures the
extent of the restraint on the heart applied by the brain. The technical
word for this is "Cardiac Vagal Tone". It is called vagal
tone because the restraint comes in the form of continuous (or tonic)
nervous impulses through a nerve, the vagal nerve. The word cardiac'
is an adjective referring to the heart and it is derived from the
Greek word "kardia" which means the heart. The NeuroScope
displays the extent of this brain restraint on the heart, or cardiac
vagal tone using a validated linear scale on a monitor screen. The
linear scale makes it easy to compare the degree of restraint, or
vagal tone, applied to the heart in various individuals or in the
same individual at different times.
