On testing for spatial correspondence between maps of human brain structure and function
A critical issue in many neuroimaging studies is the comparison between brain maps.
Nonetheless, it remains unclear how one should test hypotheses focused on the overlap or spatial …

[PDF][PDF] Modular segregation of structural brain networks supports the development of executive function in youth
The human brain is organized into large-scale functional modules that have been shown to
evolve in childhood and adolescence. However, it remains unknown whether the underlying …

Topologically dissociable patterns of development of the human cerebral cortex
SN Vandekar, RT Shinohara, A Raznahan… - Journal of …, 2015 - Soc Neuroscience
Over 90 years ago, anatomists noted the cortex is thinner in sulci than gyri, suggesting that
development may occur on a fine scale driven by local topology. However, studies of brain …
