Caption: Light micrograph of interneuron (left) and pyramidal neuron (right) in the mammalian hippocampus. Two types of nerve cells (interneuron and pyramidal neuron) from the hippocampus CA1 region have been stained with Cajal Golgi stain. The interneuron (inhibitory interneuron - left cell) is oval in shape with multiple dendrites projecting in to the basal CA1 region. A single axon is seen projecting in to the CA1 pyramidal cell and dendritic layers. The hippocampus pyramidal neuron (excitatory neuron - right cell) has a triangular cell body with a large primary dendrite (apical dendrite) extending from the cell body. It also has several dendrites projecting into the basal CA1 region. One long axon usually extends from this basal region. Dendrites gather information for processing by the cell body. After processing, information is passed on through the cell's axon. The hippocampus has the shape of a curved tube in most mammals. It has shape similar to a seahorse and has localized subdivisions CA1 through CA4. The hippocampus is an extension of the edge of the cerebral cortex. The structures that line the edge of the cortex make up the so-called limbic system, that include the hippocampus, cingulate cortex, olfactory cortex, and amygdala. The hippocampus plays important roles in the consolidation of information from short-term memory to long-term memory and spatial navigation. Other activities governed by the limbic system include memory formation, reproduction, expression of fear, rage, and pleasure.
