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.

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.
What is Cortisol? Cortisol is a steroid hormone that is produced in the adrenal cortex. The test done to ascertain the levels of this steroid hormone is known as a cortisol level test. The adrenal cortex releases this particular hormone as a response to the ACTH hormone which is secreted by the pituitary gland.
