Abstract

Although first described over a century ago, the centrifugal visual system(CVS) projecting to the retina still remains somewhat of an enigma with regard to its functional role in visually-guided behavior. The highly developed avian CVS has been the most extensively investigated and the anatomical organization of its two component centrifugal structures, the n. isthmo-opticus (NIO) and ectopic neurons (EN), including its afferent brainstem projections is reviewed. The results of double-labeling studies combining axonaltracing techniques and immunohistofluorescence have demonstrated GABA immunoreactivity (-ir) of interneurons within the neuropilar zone of the NIO, choline acetyltransferase (ChAT)-ir and nitric oxide synthase (NOS)-ir in the centrifugal cells of the NIO and EN as well as in the afferent projectionneurons of layers 9/10 of the optic tectum. The data are discussed in terms of neurochemical and excitatory/inhibitory mechanisms within the different components of the avian CVS in relation to hypotheses which have implicated this system in visual attention and ground-feeding behavior.
