The symptoms of Parkinson's Disease appear when the dopamine levels in the brain decline. Dopamine is produced in the brain in the Substantia Nigra, which is located deep in the brain, and is one of the parts of a bigger area called the "basal ganglia".
In Parkinson's, the cells of the Substantia Nigra lose power and their dopamine production slowly declines.
The images below show where the Substantia Nigra is located. The images are taken from different angles and collectively show just how deep inside the brain this area is.
Plastic – not too thin as these can split when you cut them.
Internal diameter at the top around 260mm (~10.5 inches). Definitely no less than 240mm (~9.5 inches) and no more than 300mm (~12inches).
Straight sides. Well, straight-ish sides
Depth of around 190mm (~7.5 inches). If you can find one of that depth, then you are saved a lot of cutting and fiddling. If you can only find buckets that are much deeper than that, like the one in the pic above, then brace yourself for some cutting and fiddling.
Colour of your choice. If it is close to Christmas, red could be nice.
It’s been longer than intended since the blog was updated. During this time, a new article by John Mitrofanis was published in April 2017, called Why and how does light therapy offer neuroprotection in Parkinson’s disease? You can download it here: Link.
This is a great article with much detail explained with great clarity. Even better, it is only two pages.
It poses two critical questions:
Can red/near infrared light protect brain cells from dying?
Early versions of our devices used LEDs of a single wavelength. Different wavelengths were tried over time, but in the early cases each device featured LEDs of a single type (and therefore wavelength).
John’s research planted the idea that multiple wavelengths could improve the outcomes being achieved, so we started making devices with two or more types of LED.
