The Retinotopic Organization of Striate Cortex Is Well Predicted by Surface Topology

Abstract

Due to an author oversight, the initially published version of the online Supplemental Information for this Correspondence incorrectly stated that Figures S2A and S2B showed pictures of an adult female spade-toothed beaked whale, and that Figures S2C and S2D showed pictures of a male. Figures S2A and S2B in fact show a juvenile male, and Figures S2C and S2D show an adult female. The Figure S2 legend has now been corrected in the Supplemental Information accordingly. The authors apologize for any confusion this error may have caused.

Representation of central and peripheral vision in the primate cerebral cortex: Insights from studies of the marmoset brain

“…As we noted in this report, when the cortical surface of the marmoset V1 is physically flatmounted or computationally flattened from a 3D reconstructed model, it assumes a stereotypical oval shape, similar to that of V1 of other primate species ( Fig. 1C; Van Essen et al, 1984;Horton and Hocking, 1996;Hinds et al, 2008;Benson et al, 2012). However, the intrinsic curvature of V1, which appears to be more prominent in the marmoset than in the macaque and the human (Schira et al, 2007;Hinds et al, 2008), would introduce systematic errors if measurements were made on the flattened surface.…”

Spontaneous activity in the visual cortex is organized by visual streams

“…On the basis of fine-scale resting-state activity patterns, the functional parcellation of the visual cortex appeared to be notably different from other parcellations based on cortical folding, retinotopy, and cytoarchitecture. The discrepancy with the cortical folding is perhaps reasonable, because the relationship between cortical morphology and functional organization is elusive and indirect, despite a developmental linkage likely between them as proposed elsewhere (Benson et al, 2012;Ronan and Fletcher, 2015). The discrepancy with visual field maps is perhaps also understandable, for the reasons elaborated in previous sections.…”

“…In this regard, the visual cortex is a rich and ideal benchmark. It has been characterized in terms of cellular architectonics (Amunts et al, 2000;Glasser and Van Essen, 2011), structural connections (Felleman and Van Essen, 1991;Salin and Bullier, 1995), cortical folding (Benson et al, 2012;Fischl et al, 2008), functional pathways (Hubel and Wiesel, 1962;Ungerleider and Haxby, 1994), and neural coding (Guclu and van Gerven, 2015;Ohiorhenuan et al, 2010). In recent studies, correlation patterns of spontaneous activity in the visual cortex have been examined and compared with retinotopy (Arcaro et al, 2015;Bock et al, 2015;Butt et al, 2013;Dawson et al, 2016;de Zwart et al, 2013;Genc et al, 2016;Gravel et al, 2014;Heinzle et al, 2011;Jo et al, 2012;Lewis et al, 2016;Raemaekers et al, 2014;Striem-Amit et al, 2015;Wilf et al, 2017;Yeo et al, 2011).…”

Morphologic changes in the anterior and posterior subregions of V1 and V2 and the V5/MT+ in patients with primary open-angle glaucoma

“…In order to distinguish the anterior and posterior subregions of V1 and V2, which separately corresponded to the peripheral and foveal vision, an anatomical template based upon the sulcal topology of the cortical surface was used in the current study (Benson et al, 2012). The template has an assigned eccentricity (and polar angle) value for each vertex in the FreeSurfer space, and can be used to create cortical surface predictions which are restricted to a particular extent of eccentricity.…”
