actually, it can take much less than 300 gs to lead to the most common form of traumatic brain injury.
There has been a fair bit of discovery in recent years and studies with athletes have shown that the amount of force and the location of the impact are not necessarily correlated to the severity of the concussion or its symptoms, and have called into question the threshold for concussion previously thought to exist at around 70–75 g's
