Scientists Discover New Role for Vitamin C in the Eye and the Brain

Submitted by dave on Tue, 07/26/2011 - 12:57pm

Optic nerve cells require vitamin C in order to function properly. Henrique von Gersdorff, Ph.D., a senior scientist at OHSU's Vollum Institute and a co-author of a new study showing how essential vitamin C is in retinal nerve cells had this to say:

We found that cells in the retina need to be 'bathed' in relatively high doses of vitamin C, inside and out, to function properly.

The God choice

Armed with new technology, scientists are peering into the brain to better understand human spirituality. What if, they say, God isn’t some figment of our imagination? Instead, perhaps brain chemistry simply reflects an encounter with the divine.

Are there limits to the duration of high quality of life? Are there limits to healthy life for a human brain? [These questions are relevalant for vision as well as cognitive health because the optic nerve is part of the central nervous system.]

Vitamin D helps the brain work well in later life

[Association between 25-hydroxyvitamin D levels and cognitive performance in middle-aged and older European men J Neurol Neurosurg Psychiatry 2009; doi 10.1136/jnnp.2008.165720]

Vitamin D may have a key role in helping the brain to keep working well in later life, suggests research published ahead of print in the Journal of Neurology Neurosurgery and Psychiatry.

Previous research indicates that inadequate vitamin D intake may be linked to poorer mental agility in the ageing brain, but the results have been inconsistent.

Stress Negatively Changes Brain Structure, Serene Impulse Positively Changes It

Research has shown that stress can physically reshape the brain, causing both extensive and long-lasting damage to the human brain. Brain cells can shrink and the connections between neurons can decrease. In short, stress causes big changes to the human nervous system. In 2008, new knowledge regarding the effects of short-term stress were measured at University of California, Irvine, and breakthrough research on the effects of long-term, chronic stress were conducted at the University of Wisconsin, Milwaukee.

Basic Background on the Optic Nerve and its Potential for Regeneration (thanks to Wikipedia)

Submitted by dave on Wed, 12/24/2008 - 6:08pm

According to a Wikipedia article about the optic nerve, the optic nerve is the second of twelve paired cranial nerves but is considered to be part of the central nervous system as it is derived from an outpouching of the diencephalon during embryonic development. Consequently, the fibers are covered with myelin produced by oligodendrocytes rather than the Schwann cells of the peripheral nervous system.
