About

Providing straightforward information pertaining to drugs, drug use & drug policy. The Grey Pages promotes drug-related literacy and advocates a system of viable and tolerant drug policies. This is my personal collection of commentaries, essays, tid-bits, and other such writings on everything ranging from drug use, drug policy and drug-myths, to drug-science, addiction, human behavior, and the workings of the human brain. I started this blog with a particular focus on opioids, and over the past year have found my interest gravitate toward the intriguing, ever-changing world of designer intoxicants (i.e. "research chemicals" or "designer drugs").

The Sympathetic Nervous System (Summary)

While the parasympathetic system mediates the body's baseline functions at rest, the sympathetic system is responsible for mobilizing the body's resources during states of stress. Simply put, while the parasympathetic branch continuously keeps the body running at baseline, activation of the sympathetic branch induces a state of arousal. At its highest level of function, this is known as "fight or flight" mode. These two branches work in contrast to one another, allowing the body's resource distribution to be shifted between "resting mode" and "arousal mode", according to its current needs.
