Answer

More subtle and apparently more common than overt hippocampal sclerosis is mossy-fiber sprouting. [11] The mossy fibers are the axons of the dentate granule neurons, and they typically project into the hilar polymorphic region and toward the CA3 pyramidal neurons. As the neurons in the hilar polymorphic region are progressively lost, their synaptic projections to the dentate granule neurons degenerate.
