“…This system is totally contra lateral in many mammals, such as cats, hedgehogs, tree shrews, and red belly squirrels [Meikle and Sprague, 1964;Singleton and Peele, 1965;Campbell et al, 1967;Wu and Shen. 1988], but is partly bilateral in Formosan monkeys [Chen et al, 1987], This system has not been found in echo-locating bats, although it exists in nonecho-locating bats [Simpson, 1984, for review].…”

“…Although studies of a number of mammals have shown a common pattern of retinal projections to several subcortical areas, the suprachiasmatic nucleus (SCN), dorsal and ventral lateral geniculate nuclei (dLGN and vLGN), pretectal complex (PRT), supe rior colliculus (SC), pulvinar nucleus, and the ac cessory optic system [Meikle and Sprague, 1964;Singleton and Peele, 1965;Campbell et al, 1967;Glickstein, 1967;Campbell, 1969;Cummings and De Lahunta, 1969;Lund et al, 1974;Takahashi, et al, 1977;Rodieck, 1979;Simpson, 1984;Cooper, 1986;Chen et al, 1987;Cooper and Magnin, 1987], the vis ual system of pangolins has not been examined. The aim of this study, therefore, was to gain data on the visual system in this group by investigating the retinal projections of Chinese pangolins (Manis pentadac tyla) by autoradiography.…”

Autoradiography was used to investigate the optic system of the Chinese pangolin, Manis pentadactyla. The pattern of retinal projections in the Chinese pangolin is similar to that described in other mammals. Each retina projects bilaterally to the suprachiasmatic nucleus, dorsal and ventral lateral geniculate nuclei, pretectal area, and superior colliculus (SC). Only contralateral projections are found to the medial, lateral, and dorsal accessory optic nuclei. The large lateral nucleus receives a dense projection from the retina and forms a compact mass on the dorsolateral area of the cerebral peduncle. The lamination of the SC could not be clearly demonstrated in the brain of the Chinese pangolin.

“…Among insectivores, the hedgehog AOS consists of IF, SF, DTN, LTN and MTN (Campbell et al, 1967;Tigges and Tigges, 1969;Dinopoulos et al, 1987). In the European mole (Talpa europaea), Lund and Lund (1965) reported that the AOS was poorly developed and consisted of barely discernible fiber bundles.…”

The accessory optic system (AOS) is formed by a series of terminal nuclei receiving direct visual information from the retina via one or more accessory optic tracts. In addition to the retinal input, derived from ganglion cells that characteristically have large receptive fields, are direction-selective, and have a preference for slow moving stimuli, there are now well-characterized afferent connections with a key pretectal nucleus (nucleus of the optic tract) and the ventral lateral geniculate nucleus. The efferent connections of the AOS are robust, targeting brainstem and other structures in support of visual-oculomotor events such as optokinetic nystagmus and visual-vestibular interaction. This chapter reviews the newer experimental findings while including older data concerning the structural and functional organization of the AOS. We then consider the ontogeny and phylogeny of the AOS and include a discussion of similarities and differences in the anatomical organization of the AOS in nonmammalian and mammalian species. This is followed by sections dealing with retinal and cerebral cortical afferents to the AOS nuclei, interneuronal connections of AOS neurons, and the efferents of the AOS nuclei. We conclude with a section on Functional Considerations dealing with the issues of the response properties of AOS neurons, lesion and metabolic studies, and the AOS and spatial cognition.

“…This five-layer plan for the pars dorsalis of Tupaia glis was adopted by G lick stein , C alvin and D oty [1966], Campbell et al [1966Campbell et al [ , 1967 and T igges [1966], The pres ent investigation has for the first time combined evidence from structural studies using the Nissl stain, and degeneration studies using the Nauta method, to demonstrate the existance of a six-layered dorsal nucleus of the lateral geniculate body in Tupaia. These findings provide new evi dence to support the reports of H assler [1966] based on observation of cytoarchitectural and normal myelin-stained slides.…”
