What is Topographic arrangement of the rotundo-entopallial projection in the pigeon (Columba livia) about?

## Abstract The tectofugal pathway (retina – optic tectum – nucleus rotundus – entopallium) is a prominent route mediating visual discrimination in diurnal birds. Several lines of evidence have shown that at the tecto‐rotundal stage this pathway is composed of multiple parallel channels. Anatomical studies show that the nucleus rotundus is composed of at least four subdivisions, according to differences in cytoarchitectonic, histochemical, and hodological properties. Each of these subdivisions is in receipt of a highly convergent, nontopographic tectal projection, originating from a distinct subset of tecto‐rotundal neurons. Physiological studies show that neurons of different subdivisions respond specifically to different visual dimensions, such as color, luminance, two‐dimensional motion, and in‐depth motion. At present it is less clear whether or to what extent this channel segregation is preserved at the telencephalic stage of the tectofugal pathway. The entopallium shows no obvious subdivisions or laminations. Nevertheless, tract‐tracing experiments show that separate portions of the entopallium receive efferent projections from different rotundal subdivisions, in a way that m
