Although this differs from the usual description of the human suprachoroidea, re-examination of human preparations discloses no difference between human and chimpanzee. in the study, published thursday in science, a team of scientists recorded the eye movements of three great ape species while the animals watched videos of a man searching for a hidden object that. The suprachoroidal lamellae are networks of flat branching elastic trabeculae bearing pigment cells.
They collectively correspond to the pectinate ligament of lower mammals. The uveal trabeculae are histologically identical to those of the human eye but are more numerous and nearly twice their diameter. The fine fibers resemble those occupying the chamber angle of the human foetus eye before their atrophy deepens the angle. The fine trabeculae are continuous with the delicate fibrous stroma of the ciliary body which extends between the circular muscle fibers and the longitudinal and oblique fibers, thus filling in the vestigial ciliary cleft. The coarse ones are like the human scleral trabeculae but are fewer. The scleral trabeculae are of two kinds, coarse and fine. The canal of Schlemm is a larger and more irregular channel than the human canal, with its endothelial lining interrupted so that its lumen becomes continuous with the trabecular spaces. This study presents the first documentation of the surface eye movements of the chimpanzee, Pan troglodytes, in order to determine the behavioral forms of eye-gaze and their saliency as signals. 2 The Mind of the Chimpanzee FTEN I HAVE GAZED into a chimpanzee's eyes and wondered what was. Although basically similar to the human, they appear to represent a stage in evolutionary development somewhat less advanced. My Thirty Years with the Chimpanzees of Gombe Jane Goodall. The chimpanzee eye corresponds closely to the human eye, the chief differences being related to the structures of the anterior chamber angle. The researchers also observed that participants of both species distinguished the eye-gaze directions of chimpanzees better when the contrast polarity of the chimpanzee eye was reversed compared to. No significant differences related to age could be identified. Abstract: Thirteen eyes of normal chimpanzees from 1-34 to 15 years of age were serially sectioned for histological study.
