A seven-week-old human baby following a kinetic object. Infant vision concerns the development of visual ability in human infants from birth through the first years of life. The aspects of human vision which develop following birth include visual acuity, tracking, color perception, depth perception, and object recognition.
Head size is approximately that of an adult's. May begin to lose "baby" (deciduous) teeth. Body is adult-like in proportion. Requires approximately 7,500 kJ (1,800 kcal) daily; Visual tracking and binocular vision are well developed. Motor development. Walks backwards, toe to heel. Walks unassisted up and down stairs, alternating feet.
Several layers such as the neural tube, neural crest, surface ectoderm, and mesoderm contribute to the development of the eye. [2] [3] [4] Eye development is initiated by the master control gene PAX6, a homeobox gene with known homologues in humans (aniridia), mice (small eye), and Drosophila (eyeless). The PAX6 gene locus is a transcription ...
In mammals, neurons in the brain that process vision actually develop after birth based on signals from the eyes. A landmark experiment by David H. Hubel and Torsten Wiesel (1963) showed that cats that had one eye sewn shut from birth to three months of age ( monocular deprivation ) only fully developed vision in the open eye.
