Document Summary
3 main types of brain cells: stem cells, neurons and glia. 5 types of neurons and 5 types of glia. There are brain diseases specifically related to neurons and specifically related to glia. Thought the brain was composed of a big net, and fluid flowed around the brain, and that"s how information was transferred. Concluded that the net was actually individual units (cells) Weren"t directly connected with each other like a net. 2 scientists working on this problem (no one knew what cells are) First scientists to get awarded together, but didn"t like each other that much. Light passed through tissue, light refracted through lens, reflected onto retina. Get a pretty good overall idea of structure/anatomy. Magnify up to 40-50x magnification and start to see the individual units cajal was talking about. Technique where tissue is stained with multiple fluorescent dyes that are tagged and recognize the parts of the cells.
