Brainbeauty: Cerebral Cortex

…May’s image shows progress on this work with three cell types being clearly labeled. What you are looking at are the lovely and complex branching astrocytes of the brain in yellow.  These star-like glial cells surround the neurons of the brain and perform a wide variety of functions in the body including repair of injuries to the brain and protection of the brain’s neurons. In cyan we see the nuclei of each of the surrounding neurons in the brain. And in red, we see the blood vessels that provide blood supply to the brain. The brain studied here is a rat model.

The image was created using a confocal microscope. Confocal microscopy take a three dimensional sample and creates an in-focus image of small layers of the larger image (60-70 layers are viewed in this image alone). It then piles the images to create a clear image of the structure of the entire sample. This provides researchers with important information on how the different materials are arranged in the sample. They can also scroll through the different layers to get a closer look at a given area….
