The Eye and the Corticalization Movement

The development of the brain and eye is a complex and interconnected process, involving several morphogenetic movements. Initially, the brain, perceived as a flat tissue, undergoes transformation through a cephalic and cervical flexion movement, followed by pontic development and telencephalization. This straightening process leads to a reorganization of tissues, moving closer to the midline, where the eye plays a central role in corticalization. The dynamic between the ascent of the brain and the descent of cardio-visceral structures is essential for understanding this transformation.

The eye, as an integral unit, is not only linked to cerebral morphogenesis but is also related to the facial system and body fascia. It receives emotional and hormonal information, highlighting the interconnection between psychological state and physiological responses. The development of the eye is marked by the appearance of the optic sulcus around the 26th day, which is stimulated by a vesicle in contact with the superficial wall. Furthermore, the tentorium cerebelli and the diaphragm of balance are crucial for establishing synchronicity between the brain and the digestive system, thus illustrating the importance of fulcrums in embryonic development.
