Oh, it creates a lot of difficulties - anxiety, difficulty with pain control etc etc. But it's still better than the patient waking up after the surgery unable to see because they got too close to a vision center.
I saw a few brain operations as a Registered Nurse The patients head is generally firmly clamped and the body relatively free The patient is well able to move and respond to requests Miss it Please Register or Log in to view the hidden image!
There was news just recently, of a person playing the guitar while his brain was worked on. Pain not in the brain but perhaps from the surface wounds? suppressed for the operation? I knocked myself out once, hitting my head on concrete, falling off my roof, much slower than a bullet, no pain, no memory of the fall, of the preceding cause even.
The brain itself has no touch or pain sensors (why would it?) Whacking one's head has a way of interfering with the recording of the most recent experiences. The transcription from experience to memory takes a non-zero length of time, so if something goes awry that interferes with the process, the memory may not get laid down. Think of unplugging your hard drive a fraction of a second after hitting the Save button.
Should not a bullet entering your skull give you a jolt equal to the recoil, before short circuiting , and then scramble all your grey matter before conscience could register?
Or putting a bullet through it Do not try this anywhere Please Register or Log in to view the hidden image!
