Concussion. Acceleration (g-forces) can exert rotational forces in the brain, especially the midbrain and diencephalon. A concussion, also known as a mild traumatic brain injury ( mTBI ), is a head injury that temporarily affects brain functioning. [ 9] Symptoms may include loss of consciousness; memory loss; headaches; difficulty with thinking ...
