Microscopes with more magnifying power enabled them to probe nerve cells in greater detail, revealing distinct compartments. Newer techniques expose the connections between nerve cells, revealing the complex organization of the brain.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.dailygalaxy.com/my_weblog/2009/11/image-of-the-day-time-travel-through-the-brain.html">In the 1980s, scientists developed fluorescent dyes to help them examine the long, thin extensions of neurons that carry information between these cells. Injected directly into the brain, the dye is incorporated into the cell membrane and transported along it, revealing the route of the nerve fiber.
