A modular organization of cortical function has been shown to underlie the tangential segregation of many inputs and outputs. Here, we present evidence that the callosal pathway in the visual cortex of the cat follows these general principles. Large injections of wheat germ agglutinin\u2010horseradish peroxidase or biotinylated dextran amine were made in areas 17 and 18, and callosal labeling was analyzed in tangential sections. The band of callosal cells and terminals straddling the border of areas 17 and 18 was not uniform but varied in density in a complicated fashion. Fluctuations in density of callosal connections became more clear 2\u20133 mm lateral or medial to the 17\/18 border, as the callosal labeling became less dense. Here, regular fluctuations with a periodicity of about 1 mm in area 17, and slightly greater than 1 mm in area 18 were apparent. Cytochrome oxidase staining in areas 17 and 18 showed a pattern of dense blobs with the same spacing as the callosal labeling in these areas, and the blobs were found to align with the patches of callosal labeling. Larger, more irregularly spaced stripes of callosal labeling extended from the lateral part of area 18 across area 19 and into more lateral visual areas. These results suggest that the callosal pathway in the cat's visual cortex has a patchy distribution similar to many ipsilateral corticocortical projections, and that the columnar system marked by cytochrome oxidase is important for the organization of (interhemispheric) corticocortical connectivity in cats. \u00a9 1994 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/cne.903470205","type":"journal-article","created":{"date-parts":[[2005,1,1]],"date-time":"2005-01-01T07:23:20Z","timestamp":1104564200000},"page":"197-210","source":"Crossref","is-referenced-by-count":34,"title":["Tangential organization of callosal connectivity in the cat's visual cortex"],"prefix":"10.1002","volume":"347","author":[{"given":"Jamie","family":"Boyd","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joanne","family":"Matsubara","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2004,10,9]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1177\/29.6.7252134"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/cne.902170308"},{"key":"e_1_2_1_4_1","doi-asserted-by":"crossref","first-page":"308","DOI":"10.1126\/science.159.3812.308","article-title":"Binocularly driven neurons in visual cortex of split\u2010chiasm cats","volume":"159","author":"Berlucchi G.","year":"1969","journal-title":"Science"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/0006-8993(83)90697-2"},{"key":"e_1_2_1_6_1","first-page":"298","article-title":"Segregated processing streams in cat visual cortex?
