How is Pain Produced?
This is explained using two approaches:
Text: Theories of pain and summaries of different aspects of
peripheral
and
central mechanisms are
presented at the beginning of each section. Links to review papers and textbooks
for further study are highlighted.
Animations:
present simplified views of some of the effects of
non-painful
and painful stimulation in the periphery by using stroking with a soft brush as
a non-painful stimulus and rubber ring castration of a male lamb as an example
of a painful stimulus.
This section is sub-divided into
central (brain and spinal cord) and peripheral (tissue)
mechanisms.
