part of cerebellar molecular layer morphogenesis cerebellar molecular layer formation The process that gives rise to the cerebellar molecular layer. This process pertains to the initial formation of a structure from unspecified parts. The molecular layer is the outermost layer of the cerebellar cortex. It contains the parallel fibers of the granule cells, interneurons such as stellate and basket cells, and the dendrites of the underlying Purkinje cells.
