layers of dentate gyrus

layers of dentate gyrus

[TA]
from the surface of the dentate gyrus, these layers are: the molecular layer [TA] (stratum moleculare [TA]), which contains dendrites of granular cells and some incoming axons from the perforant pathway, the granular layer [TA] (stratum granulare [TA]), which contains the layer of small granular cells, and the multiform layer [TA] (stratum multiforme [TA]), also sometimes called the polymorphic layer, which contains axons of granular cells and some afferent axons entering via the fornix.
Synonym(s): strata gyri dentati [TA]

Because we previously demonstrated in albino Swiss mice model of prion disease that astrocytes from the polymorphic layer of dentate gyrus exhibit intense reactive astrocytosis earlier than all other layers of dentate gyrus and that this change was associated with axonal degeneration of mossy fiber, we thought polymorphic layer and CA3 (target of mossy fibers) may exhibit the earliest astroglial pathology of the hippocampal formation of albino Swiss mouse model of prion disease.
