Hi again, thanks for the replies to my original question, i think i
understand what you said.So i would like to make some further pints to
clarify what i have been told:
1)So, a person using drugs, or someone feeling pain in their
heads, might feel as if the pain's originating from their brains,but
in actuality the pain is from an area adjacent to the brain,such as
the membranes surrounding the brain? Does that mean these tissues can
feel pain? If so, during the preliminary stages of brain sugery,whilst
the skin around the head and membranes/tissues around the brain are
being cut,the patient needs anaesthesia administered to him? And once
the surgeon reaches the brain there is no need for anaesthesia then?
2)For the pain to originate in the areas near the brain,but to be
actually perceived as if coming from the brain is a little odd.For a
human,the brain is arguably the most vital organ,and yet a person is
not even able to sense whether the pain of a headache or the euphoria
from cocaine is from the brain or from the spinal cord or from the
tissues surrounding the brain.How is it such an incredibly complex
organ like the brain can mis-interpret the origin of relatively simple
sensations?
Sorry if my questions seem odd, or as if i'm being too fussy, but i
just don't understand why the brain can't sense the origin of these
signals.
Thanks and bye.
