Reproducibility of Connectivity Based Parcellation - Primary Visual Cortex

Jrmy Lecoeur¹, Madhura Ingalhalikar¹, Ragini Verma¹

This study investigates the stability of cortical connectivity based parcellation over time. Such parcellations provide a unique characterization of the brain and it is believed that any change can be interpreted as being introduced by pathology or development. Hence a parcellation profile for a person could be defined using this paradigm and that constitutes a first step in quantifying differences between subjects, facilitating a meaningful clinical study. We demonstrate that such parcellation for the primary visual cortex is replicable over time with high similarity scores between the obtained clusters with an unsupervised algorithm.
