Recap
• All pain experiences are a normal response to
what your brain thinks is a threat.
• The amount of pain you experience does not
necessarily relate to the amount of tissue
damage.
• The construction of the pain experience of the
brain relies onmany sensory cues.
• Phantom limb pain serves as a reminder of
the virtual limb in the brain.
Recap
•
Danger sensors are scattered all over the body.
•
When the excitement level within a neurone
reaches the critical level, amessage is sent
towards the spinal cord.
•
When a dangermessage reaches the spinal
cord it causes release of excitatory chemicals
into the synapse.
•
Sensors in the dangermessenger neurone are
activated by those excitatory chemicals and
when the excitement level of the danger
messenger neurone reaches the critical level,
a dangermessage is sent to the brain.
•
Themessage is processed throughout the brain
and if the brain concludes you are indanger and
youneed to take action, itwill produce pain.
•
The brain activates several systems that work
together to get you out of danger.
