The Unappreciated, Holding Our Lives in Balance

Posted by Kerrie Denner


Published: October 27, 2008

If you want to glimpse the handiwork of one of your body’s unsung sensory heroes, try this little experiment. Hold your index finger a few inches in front of your face and sweep it back and forth at a rate of maybe once or twice a second. What do you see? A blurry finger. Now hold your finger steady and instead shake your head back and forth at the same half-second pace. This time, no blur, no Marcel Duchamp’s “Nude Descending a Staircase” effect. The finger stays in focus even as your head vigorously pantomimes its denial.

My Dental Appointment

So I had to go to the dentist today...I hate going to the dentist.  I totally avoided it in the beginning when I was sick, but I figured I didn't want to add dental problems to my health picture.  I do try to take really good care of my teeth, but I think a professional dental cleaning is important.  I know going to the dentist is unpleasant for a lot of people, but for me and I think others with vestibular disorders, it's especially challenging.

Researchers explore gene expression in normal vestibular nerves, vestibular schwannomas

Posted by Kerrie Denner

Researchers from the University of Toronto, directed by Drs. Gelareh Zadeh and Boris Krischek, investigated gene expression in normal vestibular nerves and vestibular schwannomas (VSs). Two important discoveries were made: 1) there is negligible difference between VSs that sporadically occur and those commonly associated with neurofibromatosis Type 2 (NF2), a genetic disorder; and 2) the overexpressed PI3K/AKT/mTOR signaling pathway in these tumors may be an excellent therapeutic target.

New test detects concussion impairments that may be overlooked

Researchers at UPMC and the University of Pittsburgh have developed a simple new test that can detect symptoms of a concussion current tests often miss.

The new test concerns the vestibular ocular system, which is responsible for integrating vision, balance and movement. It’s what allows us to keep our eyes focused and stable when we move our head around. It’s located in the vestibulum of the inner ear.
