Why are some people sensitive to Light, Sound and have Skin over-sensitivity?
Oversensitivity to Light and Sound and have Skin oversensitivity
The thalamus sits in the middle of the brain and it’s main function is to relay motor and sensory signals to the cerebral cortex.
Signals from the body go to the Thalamus first like letters going to the Post Office for distribution. Then these signals are distributed to where they need to go in the cortex of the brain.
20% of the brain's blood goes up through the back of the neck. 80% goes up through the front and gets distributed to other parts of the brain via the Circle of Willis.
The Circle of Willis takes blood from the front area of the brain back to the middle and back of the brain. A lot of people have anatomical variations to their Circle of Willis. If you have an anatomical variation to your Circle of Willis (where it does not distribute the blood well) plus have had whiplash or bad posture or a reason to slow the blood passing up through the back of your neck then there can be a problem.
The Thalamus must have fresh oxygenated blood to function. If the Circle of Willis is not distributing blood as well as it should to the Thalamus, the Cortex does not receive the sensory information it needs. The letters don’t get delivered.
So your sight can be affected like in migraines where you have little blind spots in your vision.
Your sense of feeling decreases or you can have numb areas.
So the Cortex nerves start to grow bigger and more active towards the Thalamus (neuroplastic activity) to try to get information from the Thalamus because the messages are not getting through from the Thalamus to the Cortex.
The hands and feet also grow more neurons (which can make you oversensitive in those areas) as the sensations are not getting through to the Thalamus.
We end up being oversensitive to light, sound and pain in the skin.
When you take morphine or pain medication (this is not to put you off taking pain killers when you need them), the cortex gets even less information. This encourages the nerves to grow even more in the cortex.
Personal Tuning breathing technique (which also teaches gentle exercises lying down) pumps oxygenated blood up to the Thalamas so the signals can be sent to the cortex. The letters can be delivered.
Then we can start to decrease the oversensitivity.
