In the version of the article initially published, the scaling of certain micrographs was incorrect and some scale bars were mislabeled.In Fig. 6, panels d and e have been replaced with corrected images and scale bars have been corrected to 5 mm (b,c,d,e); in panels i and m, scale bars have been corrected to 1,000 m.In the Fig. 6 legend, the coronal and cortical slice descriptions now read 2.6 mm thick.In Supplementary Fig. 10, scale bars have been corrected to 1 mm (a and b) and 2 mm (c and d).In the description, the coronal slice view is 2.6 mm thick.In Supplementary Fig. 11, images have been replaced with corrected views and scale bars are corrected to 10 mm.In the description, the coronal slice view is 2.6 mm thick.In the Supplementary Videos 5 and 6, images have been replaced with corrected views and the scale bars have been corrected to 5,000 m.
