Sneezing at the sun

From the consequential to the less so...

About a quarter of humanity will sneeze after being in the dark and then being exposed to the sun. Why we do this has yet to be understood, and, really, hasn't had much investigation, for understandable reasons. In this week's PLOS One, investigators from Switzerland tried to figure this out. In a simple experiment, they took ten known 'photic sneezers' and matched them by age and sex with non-photic sneezers. They then showed them a checkerboard display or a bright photic stimulus, and measured their electroencephalogram patterns.

Their findings? Photic sneezers, when exposed to a bright stimulus, had increased excitability of the visual cortex, not in the brainstem or lower centers of the brain, meaning that higher brain controls are responsible for this, not reflexive controls. Why some people photic sneeze and others don't and what this means in terms of neural pathways, remains unclear. Most importantly of all, however, I just learned that there is a proposed ACHOO acronym, meaning Autosomal Cholinergic Helio-Ophtalmologic Outburst, signifying the powers of acryonyms to confuse people even more.

  6. I never knew people still have powers and make things happened this way. My name is Joy Samson . from USA. Before giving birth, my Husband left me for another woman for three months, ever since then my life was filled with pains and sorrow because he was the best thing that can ever happen to me in this world and I can’t imagine my child growing up without a father, this world became one cruel place for me as at that time. About two weeks ago, a friend of mine told me he saw some testimonies of this great Dr ADAGBA that he can bring back lover within 48 hours, I laughed over it and said I am not interested but because of the love my friend had for me, she convinced me to make contact with Dr ADAGBA OF dagbaspiritualtemple@gmail.com or adagbaspiritualtemple@yahoo.com, after all I had nothing to lose. The moment Dr ADAGBA replied my message, although I was doubtful because of i have not done this before but I felt hope. I got a call from my husband 2 days after contacting Dr ADAGBA, my husband wanted to come back home and he was filled with regrets for leaving me and the child. Surprisingly, that was his first call for over 9 months and he was all sorry and kept apologizing. I was filled with joy and happy heart. I still can't believe it, because it’s highly unbelievable it’s just too real to be true but that’s it. Thank you Dr for bringing back my lover.

  7. Good day everyone, i'm Maria, If getting herpes cure was that easy then why do a lot of people still suffer from herpes?. i was diagnosed of herpes back in 2013 and i was also told it has no cure, i have been leaving with it since then, but i kept praying and doing everything possible to get cured, so i never stopped doing research about finding a cure, i came across testimonies about people getting cured through herbal medication, and i have always believe in herbs and its medical properties, after doing so many research about it i found Dr. Bulukona and i discovered he was a professional in herbal medication and he has also helped many people, i contacted him through his Website: bulukonasolutiontemple.webs.com, we talked on phone and i confirmed he was genuine, i did all what he told me to do, i received the medicine, used it as he has prescribed, and glory be to God almighty i am completely cured, i went back to my doctor to confirm it. Do not be deceived THERE IS A CURE FOR HERPES, doctors might tell you there is no cure but WITH HERBAL MEDICATION THERE IS A CURE and if you need it contact Dr. Bulukona Email: bulukonasolutiontemple@outlook.com
