Hippocampus tissue. Confocal light micrograph of a section through the hippocampus of the brain. Neurons (nerve cells) have been labelled with green fluorescent protein. Neurons are responsible for passing information around the central nervous system (CNS) and from the CNS to the rest of the body. Also seen are ion channels (gold) that allow the exchange of sodium and calcium ions across the cell membrane. This exchange propagates nerve impulses. The hippocampus is involved in memory, spatial navigation and learning.
