Compound action potentials in the peripheral nerve induced by shock-waves. 1982

H D Wehner, and K Sellier

Projectiles hitting the human body cause shock waves spreading throughout the tissue. To verify a presumed interaction between these shockwaves and nervous tissue electrophysiological experiments have been performed showing the following results: 1. Compound action potentials (CAPs) are provoked in the peripheral nerves by the shockwaves. 2. The amplitude of the CAPs correspond to the magnitude of the shockwaves. 3. There is no electrical activity in the peripheral nerves below a certain threshold pressure. 4. "Saturation effect" is occurring beyond a certain pressure limit.

UI	MeSH Term	Description	Entries
D010525	Peripheral Nerves	The nerves outside of the brain and spinal cord, including the autonomic, cranial, and spinal nerves. Peripheral nerves contain non-neuronal cells and connective tissue as well as axons. The connective tissue layers include, from the outside to the inside, the epineurium, the perineurium, and the endoneurium.
