Outer nuclear layer do not present any cross-striation, but contain a pyriform nucleus, which almost completely fills the cell. From the inner extremity of the granule a thick process passes into the outer plexiform layer, and there expands into a pyramidal enlargement or foot plate, from which are given off numerous fine fibrils, that come in contact with the outer processes of the cone bipolars. Outer nuclear layer The outer nuclear layer (or layer of outer granules or external nuclear layer), is one of the layers of the vertebrate retina, the light-detecting portion of the eye. Like the inner nuclear layer, the outer
Development of the human cerebral cortex Development of the human cerebral cortex Corticogenesis is the process in which the cortex of the brain is created during neurodevelopment. The cortex is the outer layer of the brain and is composed of up to six layers. Neurons formed in the ventricular zone migrate to their final locations in one of the six layers of the cortex The process occurs from embryonic day 10 to 17 in mice and between gestational weeks seven to 18 in humans. The preplate is the first stage in corticogenesis prior to the development of the cortical plate. The preplate is located between the
