Modelling the Neuroanatomical Progression of Alzheimer's Disease and Posterior Cortical Atrophy

Authors: Razvan V. Marinescu

arXiv

In order to find effective treatments for Alzheimer's disease (AD), we need to identify subjects at risk of AD as early as possible. To this end, recently developed disease progression models can be u...

Early features associated with the neurocognitive development at 36 months of age: the AuBE study

Authors: Sabine Plancoulaine, Camille Stagnara, Sophie Flori, Flora Bat-Pitault, Jian-Sheng Lin, Hugues Patural, Patricia Franco

arXiv

Background. Few studies on the relations between sleep quantity and/or quality and cognition were conducted among pre-schoolers from healthy general population. We aimed at identifying, among 3 years...

Dynamic Brain Functional Networks Guided By Anatomical Knowledge

Authors: Suprateek Kundu, Jin Ming, Jennifer Stevens

arXiv

Recently, the potential of dynamic brain networks as a neuroimaging biomarkers for mental illnesses is being increasingly recognized. However, there are several unmet challenges in developing such bio...

Jointly Discriminative and Generative Recurrent Neural Networks for Learning from fMRI

Authors: Nicha C. Dvornek, Xiaoxiao Li, Juntang Zhuang, James S. Duncan

arXiv

Recurrent neural networks (RNNs) were designed for dealing with time-series data and have recently been used for creating predictive models from functional magnetic resonance imaging (fMRI) data. Howe...

Preliminary Assessment of hands motor imagery in theta- and beta-bands for Brain-Machine-Interfaces using functional connectivity analysis

Authors: Jorge Antonio Gaxiola Tirado

arXiv

The use of time- and frequency-based features has proven effective in the process of classifying mental tasks in Brain Computer Interfaces (BCIs). Still, most of those methods provide little insight a...

A Differential Degree Test for Comparing Brain Networks

Authors: Ixavier A Higgins, Ying Guo, Suprateek Kundu, Ki Sueng Choi, Helen Mayberg

arXiv

Recently, graph theory has become a popular method for characterizing brain functional organization. One important goal in graph theoretical analysis of brain networks is to identify network differenc...

Topological Brain Network Distances

Authors: Moo K. Chung, Hyekyoung Lee, Andrey Gritsenko, Alex DiChristofano, Dustin Pluta, Hernando Ombao, Victor Solo

arXiv

Existing brain network distances are often based on matrix norms. The element-wise differences in the existing matrix norms may fail to capture underlying topological differences. Further, matrix norm...

On sound-based interpretation of neonatal EEG

Authors: Sergi Gomez, Mark O'Sullivan, Emanuel Popovici, Sean Mathieson, Geraldine Boylan, Andriy Temko

arXiv

Significant training is required to visually interpret neonatal EEG signals. This study explores alternative sound-based methods for EEG interpretation which are designed to allow for intuitive and qu...

Prediction of severity and treatment outcome for ASD from fMRI

Authors: Juntang Zhuang, Nicha C. Dvornek, Xiaoxiao Li, Pamela Ventola, James S. Duncan

arXiv

Autism spectrum disorder (ASD) is a complex neurodevelopmental syndrome. Early diagnosis and precise treatment are essential for ASD patients. Although researchers have built many analytical models, t...

Temporal connection signatures of human brain networks after stroke

Authors: Catalina Obando, Charlotte Rosso, Joshua Siegel, Maurizio Corbetta, Fabrizio De Vico Fallani

arXiv

Plasticity after stroke is a complex phenomenon initiated by the functional reorganization of the brain, especially in the perilesional tissue. At macroscales, the reestablishment of segregation withi...

Tracing Network Evolution Using the PARAFAC2 Model

Authors: Marie Roald, Suchita Bhinge, Chunying Jia, Vince Calhoun, Tülay Adalı, Evrim Acar

arXiv

Characterizing time-evolving networks is a challenging task, but it is crucial for understanding the dynamic behavior of complex systems such as the brain. For instance, how spatial networks of functi...

Cross-population coupling of neural activity based on Gaussian process current source densities

Authors: Natalie Klein, Joshua H. Siegle, Tobias Teichert, Robert E. Kass

arXiv

Because local field potentials (LFPs) arise from multiple sources in different spatial locations, they do not easily reveal coordinated activity across neural populations on a trial-to-trial basis. As...

Same Cause; Different Effects in the Brain

Authors: Mariya Toneva, Jennifer Williams, Anand Bollu, Christoph Dann, Leila Wehbe

arXiv

To study information processing in the brain, neuroscientists manipulate experimental stimuli while recording participant brain activity. They can then use encoding models to find out which brain "zon...

Tests for partial correlation between repeatedly observed nonstationary nonlinear timeseries

Authors: Kenneth D. Harris, Alex E. Yuan

arXiv

We describe two families of statistical tests to detect partial correlation in vectorial timeseries. The tests measure whether an observed timeseries Y can be predicted from a second series X, even af...

Ranking of Communities in Multiplex Spatiotemporal Models of Brain Dynamics

Authors: James Wilsenach, Katie Warnaby, Charlotte M. Deane, Gesine Reinert

arXiv

As a relatively new field, network neuroscience has tended to focus on aggregate behaviours of the brain averaged over many successive experiments or over long recordings in order to construct robust...
