Phantoms in the Brain By analyzing different kinds
of brain damage, and the feelings associated with phantom limbs (people with
missing limbs can still feel pain in those non-existent limbs), the Indian
neurologist Vilayanur Ramachandran concluded that the brain
constructs cognitive maps that are, basically, plausible interpretations of the
world. It is those maps that cause all mental life, starting from perception
itself. For example, the limb is no longer there, but its representation in the
brain is still there, and thus the person feels it as if it were still there.
Whether it is truly there or not is negligible compared with the fact that it
is represented in the brain. By generalization all mental life could be
"phantom", because that is a general behavior of the brain. All sensory experience is an
illusion. All feelings are illusions. Even the self consists of an illusion,
largely constructed out of interactions with others. The brain creates these
representations of different kinds (from representations of limbs to
representations of the i) and then believes that they truly exist and they get
associated with feelings. (Thus the solution to the pain caused by a phantom
limb would be to induce the brain to believe that the phantom limb does not
exist anymore, i.e. to remove the representation of that limb in the brain). In a sense, the entire body is a "phantom
limb": the brain constructs its existence and then "feels" it. Back to the beginning of the chapter "Inside The Brain" | Back to the index of all chapters |
