Dictionary of Biological Psychology
There are two groups of mossy fibres in the brain. One is the mossy fibres in the HIPPOCAMPUS, which are axons of GRANULE CELLS in the DENTATE GYRUS. They course laterally and terminate in the stratum lucidum of the CA3 region (see CA1–CA3) of the hippocampus.
The second group of mossy fibres is in the CEREBELLUM. These mossy fibres represent one class of AFFERENT to the CEREBELLAR CORTEX. Their terminal endings are called rosettes. Rosettes make multiple synaptic contacts with various neuronal elements in the granular layer, in a complex nodular arrangement called a GLOMERULUS.
