Post 2

   I found that one of the more interesting chapters was the one on color perception. After researching the topic some, I found a great article that relates to it.

  In 2005, the first images of human retinas lead to a suprise about how we percieve the world. "Researchers at the University of Rochester found that the number of color-sensitive cones in the human retina differs dramatically among people—by up to 40 times—yet people appear to perceive colors the same way" (DailyScience 1). These findings lead to the suggestion that our color perception is controlled much more by our brain than our eyes.

  One of the professors stated, "We were able to precisely image and count the color-receptive cones in a living human eye for the first time, and we were astonished at the results. We've shown that color perception goes far beyond the hardware of the eye, and that leads to a lot of interesting questions about how and why we perceive color."
 " This professor and his research team, led by postdoctoral student Heidi Hofer, now an assistant professor at the University of Houston, used a laser-based system developed by Williams that maps out the topography of the inner eye in exquisite detail. The technology, known as adaptive optics, was originally used by astronomers in telescopes to compensate for the blurring of starlight caused by the atmosphere" (DailyScience 2).
