The adjective internal is used in opposition to the external granular layer of the cortex.

The external granular layer (II) is relatively dense.

The external granular layer of the cerebral cortex is commonly known as layer II.

Lamina granularis externa is layer 2, or the external granular layer, of the cerebral cortex.

The second germinal zone (cellular birthplace) is known as the Rhombic lip, neurons then move by human embryonic week 27 to the external granular layer.

Layer II, the external granular layer, contains small pyramidal neurons and numerous stellate neurons.

The external granular layer ceases to exist in the mature cerebellum, leaving only granule cells in the internal granule layer.

The external granular layer is one of the layers of the cerebellar cortex consisting of granule cells, which are also known as granular neurons.

Apical dendrites from pyramidal cells in the external granular layer and more prominently the external pyramidal layer project into the molecular layer.

The second and third layers, or the External Granular layer and External Pyramidal layer respectively, are formed around mouse E13.5 to E16.

For example, in the external granular layer (EGL), where mitosis of cerebellar granular neuron occurs, CRMP-2 is highly expressed while CRMP-5 is never expressed.

His name is lent to the eponymous "line of Kaes", which is a thin band of myelinated fibers located between the external granular layer and the external pyramidal layer of the cerebral cortex.

He described the locus coeruleus, the locus niger in the brain, in 1786, and the band of Vicq d'Azyr, a fiber system between the external granular layer and the external pyramidal layer of the cerebral cortex, as well as the Mamillo-thalamic tract, which bears his name.
