Dentate gyrus
The dentate gyrus is part of the hippocampus and acts as its "input station." It receives various sensory inputs from the cortex (cerebral cortex) via the entorhinal cortex. Its densely packed granule cells, which are found in the so-called granular layer, project almost exclusively to the CA3 region of the hippocampus.

Hippocampus
The hippocampus is the largest part of the archicortex and an area in the temporal lobe. It is also an important part of the limbic system. Functionally, it is involved in memory processes, but also in spatial orientation and learning. It comprises the subiculum, the dentate gyrus, and the Ammon's horn with its four fields CA1-CA4. Changes in the structure of the hippocampus due to stress are associated with chronic pain. The hippocampus also plays an important role in the amplification of pain through anxiety.

Mossy fiber
Mossy fibers are nerve fibers that conduct impulses from the spinal cord and the pontine nuclei to the cerebellum. There they terminate in the granule cell layer. The axons of the granule cells of the dentate gyrus in the hippocampus, which extend to CA3, are also referred to as mossy fibers.
