Abstract:
It is hypothesized that there is an entity properly called 'concussion', a transient loss of neuronal function without permanent neuronal damage, as defined years ago by Derek-Denny Brown. This implies that multiple concussions leave no deficit. n +1 times zero is still zero. Arguments are presented indicating that there is a margin of safety between the acceleration inducing 1-10 s loss of function (concussion) and that inducing permanent damage (contusions, lacerations).
