Blood flow in rat brain capillaries: Two-photon microscopy

This movie shows the movement of red blood cells in capillaries of the rat cortex. It was taken using a technique called in vivo two-photon laser scanning microscopy. The blood serum was labeled with a fluorescent dye (blood cells are not labeled and appear as shadows), while the astrocytes, that form the blood brain barrier, were labeled with sulforhodamine 101. Our laboratory applied methods of quantifying blood flow at the level of individual blood vessels, in order to study functional regulation of blood flow in brain.

Thanks for the question. Those aren't the actual colours of the brain. We artificially labeled the blood vessels and surrounding cells with fluorescent dyes to to help us visualize them under the microscope.

what makes it that color? or is it that color?

very cool
