I would disagree with that.
The brain and how it functions is poorly understood. Many discoveries about the brain lay ahead of us. I don't know that medical theories explain every NDE case but one must first look for medical exlanations.
I challenge you to read Pam Reynold’s NDE and try to come up with ANY rational explanation for what she remembered or visualized during her operation and NDE.
Ok. From the article:
Spetzler would bring Pam’s body down to a temperature so low that she was essentially dead.In cases of hypothermia, the person near the end stage suddenly gets a feeling of warmth and well being. Death for such person is near. This ties in with my earlier speculation that NDE's may have something to do with the brain in it's final acts of shutting down easing the departure by creating a sense of peace.
Her brain would not function, but it would be able to survive longer without oxygen at this temperature.One might say death only occurs at a point which the person can no longer be revived and all bodily function ceases. The body is an enormously complex electro-chemical system. As is well known with drowning victims, cardio-pulmonary function may cease for some time yet the victim can still be resuscitated. Just because normal brain activity cannot be detected doesn't mean some failsafe mechanism exists that is responsible for NDE reports.
Recall from your middle school biology class when you dissected frogs. After removing the beating heart, the heart would continue beating for quite some time in a petri dish of water. Similarly, the brain has a poorly understood ability to maintain some level of functionality after cardio-pulminary function ceases.
When a person is placed under general anaesthesia, my understanding is they are only given "just enough" to put them under. The amount "just enough" varies. Some patients may experience a partial revival, or be so near the threshold as to be like a dimly flickering incandescent lightbulb.
Even though eyes are taped shut, The surgical light above them may appear through taped eyelids as a tunnel leading to a bright light. Even with headphones playing music or other noises, a patient may still hear via bone conduction. The patient will be on a ventilator, a breathing tube inserted into their mouth and throat. Teeth will be in contact with the tube. This is one path for bone conduction. Other surgical instruments may be in contact with bone thereby providing conduits for operating room sounds to be transmitted to the patient.
Once the patient was under, the earphones may have been turned off, disconnected or maladjusted thereby permitting normal hearing.
The brain in it's suppressed state struggles to make sense of the scattered stimuli it receives. Still struggling to understand what is happening, it switches to a "third person" mode whereby it tries to take a different perspective of what is happening. This "third person" view may account for the out of body experiences commonly reported by those having near death experiences.
For crying out loud. You are grasping at ephemeral straws. She was clinically DEAD.
Why don’t you put a blindfold on and describe what is going on in the room - and you are not even clinically dead.
In that same article another person - clinically dead - described a shoe on a ledge outside the hospital. She described the position of the shoe and was insistent to her nurse on finding out if such a shoe was there.
The nurse went to check and indeed there was a shoe there just as she described. The shoe was in no way visible from inside the room.
It is obvious you are not very well read on the topic of NDE’s. I suggest you get more informed before presenting your implausible scenarios. Just saying the body is complex is not an answer. And a dissected frog does not have consciousness.
