Techniques for Analysis of Folding Development in the Cerebral Cortex

Speaker: Rosita Shishegar, University of Melbourne

Talk Title: Techniques for Analysis of Folding Development in the Cerebral Cortex

Series: Medical Imaging Seminar Series

Abstract: Gyrification describes the series of events through which the immature cortex develops from a smooth surface to a folded sheet. While there is considerable speculation about the biological mechanisms that underpin the formation of gyri and sulci, little known about the events that directly lead to folding. In this talk, Rosita Shishegar will introduce the open problems in understanding cortical gyrification and provide an overview of a research program aimed at expanding knowledge in this area through the longitudinal study of brain development in the fetal sheep. In particular, she will focus on tools for morphometric analysis of the structural and diffusion-weighted MRI data, and present a new gyrification index derived from Laplace Beltrami eigenfunction level sets that combines the strengths of surface-based and curvature-based gyrification metrics.
