Altered Topological Structure of the Brain White Matter in Maltreated Children through Topological Data Analysis

1 code implementation12 Apr 2023 Moo K. Chung, Tahmineh Azizi, Jamie L. Hanson, Andrew L. Alexander, Richard J. Davidson, Seth D. Pollak

Childhood maltreatment may adversely affect brain development and consequently influence behavioral, emotional, and psychological patterns during adulthood.

no code implementations19 Feb 2019 Yilin Liu, Gengyan Zhao, Brendon M. Nacewicz, Nagesh Adluru, Gregory R. Kirk, Peter A Ferrazzano, Martin Styner, Andrew L. Alexander

However, most of the previous deep learning work does not investigate the specific difficulties that exist in segmenting extremely small but important brain regions such as the amygdala and its subregions.

Diffeomorphic Metric Mapping and Probabilistic Atlas Generation of Hybrid Diffusion Imaging based on BFOR Signal Basis

no code implementations25 Sep 2013 Jia Du, A. Pasha Hosseinbor, Moo. K. Chung, Barbara B. Bendlin, Gaurav Suryawanshi, Andrew L. Alexander, Anqi Qiu

In this work, we show that the reorientation of the $q$-space signal due to spatial transformation can be easily defined on the BFOR signal basis.
