Chen, the 18-year-old who became U.S. champion with a score 40 points higher than the rest of the competition, was a no-doubt choice. With a five-quad program that is pushing the sport to literal new heights, Chen is the best American hope for a singles figure skating medal. âItâs been a dream of mine to be selected on the U.S. Olympic team as long as I can remember,â Chen said. âThe Olympics have really motivated me, ever since I started skating as a little kid.â [Nathan Chen secures first at U.S. nationals. Chaos reigns in his wake.]
Cortical neurons are the cells of the brain's largest region, the two hemispheres of the cerebral cortex. Most of the complex activity of the brain enabling thought, perception, and voluntary movement is connected to the activity of these neurons.
The organ of Corti lies within the middle chamber of the cochlea. It contains thousands of hair cells, which are the actual vibration receptors. The apical surface of the hair cells contains an array of stereocilia, which give the hair cells their name. Stereocilia are not built from the 9+2 arrangement of microtubules that are found in true cilia. The hair cells are located between the basilar and tectorial membranes.
