Spinal cord concussion.
A reliable experimental model using decerebrate frogs has been developed by which a measured cutaneous stimulus to the right forelimb produces a single electrical response from the left sciatic nerve. Using this model, the minimal concussing force necessary to abolish the propagation of the nerve impulse down the spinal cord was established by trial and error. The mean recovery time was 31.2 seconds, with a standard deviation of 1.32 seconds. Recovery of function of the spinal cord, as measured this method, was complete following single and multiple concussions.
