Atlases are essential in providing a <span class=\"highlight\">common<\/span> space for interpretation of results across studies, for anatomical education, and providing quantitative image-<span class=\"highlight\">based<\/span> navigation. Extensive work has been devoted to <span class=\"highlight\">atlas<\/span> construction for humans, macaque, and several non-primate species (e.g., rat). One notable gap in the literature is the <span class=\"highlight\">common<\/span> <span class=\"highlight\">squirrel<\/span> <span class=\"highlight\">monkey<\/span> &#8211; for which the primary published atlases date from the 1960&#8217;s. The <span class=\"highlight\">common<\/span> <span class=\"highlight\">squirrel<\/span> <span class=\"highlight\">monkey<\/span> has been used extensively as surrogate for humans in biomedical studies, given its anatomical neuro-system similarities and practical considerations. This work describes the continued development of a multi-modal MRI <span class=\"highlight\">atlas<\/span> for the <span class=\"highlight\">common<\/span> <span class=\"highlight\">squirrel<\/span> <span class=\"highlight\">monkey<\/span>, for which a structural <span class=\"highlight\">imaging<\/span> space and gray <span class=\"highlight\">matter<\/span> parcels have been previously constructed. This study adds <span class=\"highlight\">white<\/span> <span class=\"highlight\">matter<\/span> tracts to the <span class=\"highlight\">atlas<\/span>. The new <span class=\"highlight\">atlas<\/span> includes 49 <span class=\"highlight\">white<\/span> <span class=\"highlight\">matter<\/span> (WM) tracts, defined using <span class=\"highlight\">diffusion<\/span> <span class=\"highlight\">tensor<\/span> <span class=\"highlight\">imaging<\/span> (DTI) in three animals and combines these data to define the anatomical locations of these tracks in a standardized coordinate system compatible with previous development. An anatomist reviewed the resulting tracts and the inter-animal reproducibility (i.e., the Dice index of each WM parcel across animals in <span class=\"highlight\">common<\/span> space) was assessed. The Dice indices range from 0.05 to 0.80 due to differences of local registration quality and the variation of WM tract position across individuals. However, the combined WM labels from the 3 animals represent the general locations of WM parcels, adding basic connectivity information to the <span class=\"highlight\">atlas<\/span>.<\/p>\n<figure id=\"attachment_535\" aria-describedby=\"caption-attachment-535\" style=\"width: 500px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-535\" src=\"https:\/\/my.vanderbilt.edu\/masi\/wp-content\/uploads\/sites\/2304\n2661\/2016\/10\/unnamed-file.jpg\" alt=\"Figure 2 The pipeline for iterative definition of one bundle \u2013 the left cingulum in native space of one monkey.\" width=\"500\" height=\"379\" \/><figcaption id=\"caption-attachment-535\" class=\"wp-caption-text\">Figure 2<br \/> The pipeline for iterative definition of one bundle \u2013 the left cingulum in native space of one monkey.<\/figcaption><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Yurui Gao, Prasanna Parvathaneni, Kurt G.
