... the ganglion cells, revealing their targets. "The labeling was just beautiful," said Yau. "It showed that the axonal projections of these cells reach out to innervate the SCN in a very dense manner. The axons also project to other areas of the brain such as the intergeniculate leaflet, which in turn connects...'Summer of the Shark in 2001 more hype than fact, new numbers show
GAINESVILLE, Fla. --- Despite Time magazine labeling it the Summer of the Shark and the prevailing perception that 2001 was a banner year for shark attacks, actual numbers were slightly down, a new University of Florida study shows. The annual total of 76 unprovoked attacks worldwide was less than t...Neural stem cells move to damaged areas of brain after injury
