“…LM and nBOR also have a diversity of efferent targets that includes the inferior olive, cerebellum, oculomotor regions, pontine nuclei and ventral tegmentum, among other structures [41] , [42] , [123] , [130] , and these projections emerge from distinct neuronal populations within nBOR and LM [131] , [132] . Similarly, GLv also has several inputs and outputs; besides efferents from the retina and TeO [38] , [39] , [133] , GLv receives projections from the Wulst [134] , [135] and projects to the dorsal thalamus [136] and the TeO [39] , [44] . Therefore, the covariation of different neural structures may depend not only on the functional connectivity of each nucleus, but also on the “exclusivity” or diversity of the connections between them.…”

Mosaic and Concerted Evolution in the Visual System of Birds

Two main models have been proposed to explain how the relative size of neural structures varies through evolution. In the mosaic evolution model, individual brain structures vary in size independently of each other, whereas in the concerted evolution model developmental constraints result in different parts of the brain varying in size in a coordinated manner. Several studies have shown variation of the relative size of individual nuclei in the vertebrate brain, but it is currently not known if nuclei belonging to the same functional pathway vary independently of each other or in a concerted manner. The visual system of birds offers an ideal opportunity to specifically test which of the two models apply to an entire sensory pathway. Here, we examine the relative size of 9 different visual nuclei across 98 species of birds. This includes data on interspecific variation in the cytoarchitecture and relative size of the isthmal nuclei, which has not been previously reported. We also use a combination of statistical analyses, phylogenetically corrected principal component analysis and evolutionary rates of change on the absolute and relative size of the nine nuclei, to test if visual nuclei evolved in a concerted or mosaic manner. Our results strongly indicate a combination of mosaic and concerted evolution (in the relative size of nine nuclei) within the avian visual system. Specifically, the relative size of the isthmal nuclei and parts of the tectofugal pathway covary across species in a concerted fashion, whereas the relative volume of the other visual nuclei measured vary independently of one another, such as that predicted by the mosaic model. Our results suggest the covariation of different neural structures depends not only on the functional connectivity of each nucleus, but also on the diversity of afferents and efferents of each nucleus.

“…Possibly, the similarities in adhesive properties relate to similarities in the lamina‐specific termination of afferent fibers. For example, tectofugal projections upon the superficial GV neuropil tend to concentrate more deeply than hyperstriatal afferents (Crossland and Uchwat, 1979; Crossland, 1981; Ehrlich et al, 1989). On the other hand, it is known that several visual brain structures in the mesencephalon and diencephalon receive somatosensory input to their intermediate and deep layers in mammals (Wiberg and Blomqvist, 1984; Rhoades et al, 1989).…”

The expression of OL‐protocadherin, a homotypically binding cell adhesion molecule, was mapped in the visual system of the chicken embryo at intermediate to late stages of development (11–19 days of incubation). The expression was compared with that of four classic cadherins, described previously. OL‐protocadherin is expressed by the isthmooptic nucleus, its retinopetal projection, and possibly its retinal target neurons, the amacrine cells. Ganglion cells begin to express OL‐protocadherin at relatively late stages of development. The layers of the optic tectum, the projection neurons in the stratum griseum centrale, and the tectofugal pathways show differential OL‐protocadherin immunoreactivity. Several of the diencephalic target nuclei of the tectothalamic projection, such as the principal pretectal nucleus, subpretectal nucleus, and nucleus rotundus, contain distinct subregions or populations of neurons expressing OL‐protocadherin. In these centers, the expression pattern of OL‐protocadherin differs from that of the four classic cadherins, though it shows partial overlap with them. Other retinorecipient and/or tectorecipient nuclei (ventral geniculate nucleus, lateral dorsolateral nucleus, superficial synencephalic nucleus, pretectal area, and griseum tectale) also show a differential immunoreactivity for OL‐protocadherin and other cadherins. Some of these nuclei and the optic tectum display a similar sequence of cadherin expression from superficial to deep layers, in a pattern that may reflect mutual interconnections. This result indicates a partial conservation of cadherin expression across interconnected embryonic divisions, from the mesencephalon to the ventral thalamus. In conclusion, OL‐protocadherin is a marker for specific functional gray matter structures and neural circuits in the chicken visual system. J. Comp.
