ANATOMY

Detailed explanation-1: -The critical period for development of stereopsis in humans is well defined. After an abrupt onset at approximately 3 months of age, 1 2 3 4 5 there is a rapid period of maturation until 8 to 18 months of age, 6 followed by a continued gradual improvement until at least 3 years of age.

Detailed explanation-2: -There are two types of stereopsis – coarse stereopsis and fine stereopsis.

Detailed explanation-3: -In humans, stereopsis has become an attractive model system for understanding the link between neural activity and perception (Roe et al., 2007; Read, 2015a). We now have a good basic understanding of the different processes of primate stereopsis and the brain areas involved (Cumming and DeAngelis, 2001).
