Something from what I learnt today!
So here's the scenario:
Patient is reported brain dead, the relative walks in and is shocked to see that the patient's toe is moving. So he goes back and gets mad at doctor. What went wrong here?
These movements are normal! A person with brain death can have spontaneous movements, these originate from peripheral nerves or spinal cord which are intact!
On the other hand the brain stem and cerebral reflexes like pupillary, oculocephalic, oculovestibular, corneal, gag etc will be absent.
