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 cerebral cortex is gray matter, consisting mainly of cell bodies (with astrocytes being the most abundant cell type in the cortex as well as the human brain as a whole) and capillaries.It contrasts with the underlying white matter, consisting mainly of the white myelinated sheaths of neuronal axons.he layered structure of the mature cerebral cortex is formed during development. The first pyramidal neurons generated migrate out of the ventricular zone and subventricular zone, together with reelin producing CajalâRetzius neurons, from the preplate.
