This is not a claim, it's a medical fact that the brainstem does not function after cardiac arrest. How can we be sure of this ?? Read the passage below, it tells you what the brainstem does and is responsible for :
brainstem, area at the base of the brain that lies between the deep structures of the cerebral hemispheres and the cervical spinal cord. It is divided into three sections: midbrain (mesencephalon), pons (metencephalon), and medulla oblongata (myelencephalon). The brainstem houses many of the control centres for vital body functions, such as swallowing, breathing, and vasomotor control. All of the cranial nerve nuclei, except those associated with olfaction and vision, are located in the brainstem, providing motor and sensory function to structures of the cranium, including the facial muscles, tongue, pharynx, and larynx, as well as supplying the senses of taste, equilibrium, and hearing. The brainstem also has nuclei important for sympathetic and parasympathetic autonomic functions. All efferent and afferent pathways between the cerebrum and cerebellum course through the brainstem, and many of them decussate, or cross, within this structure. Because of the important neural structures concentrated in this small portion of the nervous system, even very small lesions of the brainstem may have profound effects. Disorders involving the brainstem include trauma, tumours, strokes, infections, and demyelination (multiple sclerosis). Complete loss of brainstem function is regarded by some experts as equivalent to brain death
Have you read that, Master Wu ? Did you read the word SWALLOWING ....is a function of the brainstem
Immediately after a person falls to the floor after cardiac arrest, the doctors can insert a tube down the patients throat AND THE PATIENT DOES NOT
GAG. His swallowing reflex is ABSENT and this is why we can say that the brain stem is not functioning at that time. It doesn't mean that function won't return but it does mean it is temporarily down. Are you going to call bullshit on me ? This is fact
Now, I've spent half an hour rooting around trying to find a paper that might be suitable to show you in a simple manner. They don't and can't do experiments on human brainstems just like that. Animals have been used instead which I don't particularly like but I will continue to search for that kind of experiment.
Yes tim, I know all that. It's what I said to you earlier. We're not talking about swallowing and having tubes put down throats. As I pointed out several times now, generation of motor reflexes is not at argument here.
