This chapter presents an overview of the avian visual system. In particular, the avian system is compared to the mammalian system by focusing on primates traditionally used in vision studies.
Birds rely heavily on vision for their high-speed flight, long-distance navigation, successful foraging, and appropriate interactions in complex social : Toru Shimizu. Scientists interested in the visual perception and cognition of birds should find it useful to consider what drove the evolution of the avian visual system.
Consideration and application of such ideas should, at some level, guide investigations of visual search, concept formation, et cetera. Citation / Publisher Attribution. The Avian Visual System: Overview, in O. Lazareva, T. Shimizu, & E.

It briefly describes the first phase, when the system is organized without much information from sensory organs. It also discusses the period when sensory information starts to affect the wiring of the visual system nuclei, and combine the development of visually guided behavior with that of the visual system.
Extraocular anatomy. The eye of a bird most closely resembles that of the reptiles. Unlike the mammalian eye, it is not spherical, and the flatter shape enables more of its visual field to be in focus. A circle of bony plates, the sclerotic ring, surrounds the eye and holds it rigid, but an improvement over the reptilian eye, also found in avian visual system book, is that the lens is pushed further forward.
For avian visual system book neural aspects of the avian visual system, studies on the telencephalon have just begun. While ample investigations have focused on the retina and well developed midbrain of the avian visual system, more physiological and anatomical data on the visual telencephalon are imperative, as it clearly plays an essential role in various visual.

Reptilian Eye. Features: As in other vertebrates including birds, the eyes of reptiles consist of an outer, fibrous and tough layer of sclera, a vascular layer called the choroid, and an inner, thin pigment epithelium that is applied to the outer surface of the neural retina.
The choroid supplies oxygen and nutrition to the retina of many reptiles, but in lizards and to a lesser extent in. The avian visual system.

This chapter presents a brief account of the functional organization of the avian visual system. It provides detail about the retina of pigeons and chicks. Both have a central retinal area of enhanced vision, where ganglion cell densities reach up to forty-one thousand cells per mm2 in the pigeon and twenty-four thousand cells per mm2 in the chick.

Lesions in the mid-brain involving the isthmo-optic nucleus result in fibre degeneration which can be traced through the isthmo-optic tract to the chiasma and thence into the contralateral optic nerve and retina. The avian visual system demonstrates that the formation of neuronal asymmetries can be caused by sensory stimulation that is asymmetrically experienced.
Monocular deprivation or intraocular applications of tetrodotoxin or BDNF suggest that lateralization develops via activity-dependent differentiation of brain circuits.

Their reliance on vision is manifested in very large eyes and a highly differenti-ated visual system, in which the visual pathways and nuclei, conforming to a common vertebrate neural Bau. The avian visual system is usually highly developed. Water birds have special flexible lenses, allowing accommodation for vision in air and water.
Some species also have dual fovea. Birds are tetrachromatic, possessing ultraviolet (UV) sensitive cone cells in the eye as well as green, red and blue ones.

There is a great online chapter covering the Evolution of the Avian Visual System by Scott Husband and Toru Shimizu covering everything from brain evolution in dinosaurs to retinal structure and post retinal pathways.
Also, if evolution of visual systems interests you, don’t forget to read the Webvision chapter Evolution of Phototransduction, Vertebrate photoreceptors and Retina by Trevor. The ability to perceive rapid movement is an essential adaptation in birds, which are involved in rapid flight, pursuing prey and escaping predators.
Nevertheless, the temporal resolution of the avian visual systems has been less well explored than spectral sensitivity. There are indications that birds are superior to humans in their ability to detect movement, as suggested by higher critical.
The avian centrifugal visual system, which project s from the brain to the retina, has been intensively studied in several Neognathous birds that have a dist inct isthmo-optic nucleus (ION). However, birds of the order Palaeognathae seem to lack a proper ION in histologically stained brain sections.

The ability to resolve rapid movement is determined by the temporal resolution of the visual system (Jones et al., ).
The book discusses various brain areas involved in processing information, focusing on the evolutionary origins and mechanics behind the several parallel pathways that compose the visual system.
Later chapters explain how the nervous system processes the perception of color, motion, depth, and s: 1.
