Sclera moving at some velocity. The cushion of orbital fat protects the sclera from head-on blunt forces, but damage from oblique forces striking the eye from the side is not prevented by this cushion. Hemorrhaging and a dramatic drop in intraocular pressure are common, along with a reduction in visual perception to only broad hand movements and the presence or absence of light. However, low-velocity injury which does not puncture and penetrate the sclera requires only superficial treatment and the removal of the object. Sufficiently small objects which become embedded and which are subsequently left untreated may eventually become surrounded by
Development of the human cerebral cortex related pattern similar to "in vivo" corticogenesis. Using immunocytochemical analysis on mouse neural stem cells derived from ESCs, after 6 days there was evidence of neuronal differentiation. The recapitulation ability only follows after the knowledge of spatial and temporal patterns have been identified, along with giving the knowledge that corticogenesis can occur without input from the brain. 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
