Now, we have to acknowledge that
the dangermessage from the tissues
via the spinal cord is just one of the
inputs to the brain. Although that
message is very important, on its own
it is not enough to cause pain.
Remember the story of phantom limb
pain (see page 22). The actual body
part doesn’t even exist, but it hurts in
fresh air. Brain imaging studies show
activity in all the same brain areas,
whether youhave the limb or not!

Many of the ignition nodes are also
activated by a wide range of stimuli
that grab your immediate
attention.

This canmake some
people with chronic pain
hypersensitive to all sorts of stimuli
such as noise, light and temperature
changes.
