Caption: Hippocampus tissue. Light micrograph of a sagittal (side view) section through the hippocampus of the brain showing the nerve cells within it. The hippocampus is a structure of the limbic system of the brain. There is a hippocampus in each cerebral hemisphere, and they are thought to be responsible for spatial awareness and the formation of memories. Different structures have been stained different colours: the nuclei of cells are red, neurofilaments are blue and glial cells are green. Neurofilaments are proteins found in the axons (output processes) of nerve cells. Glial cells (neuroglia) are cells that support and nourish nerve cells. Magnification: x160 when printed 10cm wide.
