Mode decomposition-based time-varying phase synchronization for fMRI Data

no code implementations26 Mar 2022 Hamed Honari, Martin A. Lindquist

Here we explore alternative approaches based on the use of various mode decomposition (MD) techniques that circumvent this issue.

Evaluating phase synchronization methods in fMRI: a comparison study and new approaches

no code implementations21 Sep 2020 Hamed Honari, Ann S. Choe, Martin A. Lindquist

One way to assess the relationship between signals from different brain regions is to measure their phase synchronization (PS) across time.

Investigating the impact of autocorrelation on time-varying connectivity

no code implementations22 Apr 2019 Hamed Honari, Ann S. Choe, James J. Pekar, Martin A. Lindquist

Although previous studies have shown that autocorrelation can negatively impact estimates of static functional connectivity, its impact on TVC estimates is not well known at this time.

Automatic Identification of Twin Zygosity in Resting-State Functional MRI

no code implementations30 Jun 2018 Andrey Gritsenko, Martin A. Lindquist, Gregory R. Kirk, Moo. K. Chung

A key strength of twin studies arises from the fact that there are two types of twins, monozygotic and dizygotic, that share differing amounts of genetic information.
