Testing Selective Influence Directly Using Trackball Movement Tasks

Authors: Ru Zhang, Cheng-Ta Yang, Janne V. Kujala

arXiv

Systems factorial technology (SFT; Townsend & Nozawa, 1995) is regarded as a useful tool to diagnose if features (or dimensions) of the investigated stimulus are processed in a parallel or serial fash...

Cord-blood vitamin D level and night sleep duration in preschoolers in the EDEN mother-child birth cohort

Authors: Chu Yan Yong, Eve Reynaud, Anne Forhan, Partricia Dargent-Molina, Barbara Heude, Marie-Aline Charles, Sabine Plancoulaine

arXiv

Objective: 25-hydroxyvitamin D (25OHD) deficiency has been associated with sleep disorders in adults. Only three cross-sectional studies were performed in children and showed an association between 25...

Anatomically-Informed Data Augmentation for functional MRI with Applications to Deep Learning

Authors: Kevin P. Nguyen, Cherise Chin Fatt, Alex Treacher, Cooper Mellema, Madhukar H. Trivedi, Albert Montillo

arXiv

The application of deep learning to build accurate predictive models from functional neuroimaging data is often hindered by limited dataset sizes. Though data augmentation can help mitigate such train...

Small-world topology of functional connectivity in randomly connected dynamical systems

Authors: Jaroslav Hlinka, David Hartman, Milan Paluš

arXiv

Characterization of real-world complex systems increasingly involves the study of their topological structure using graph theory. Among global network properties, small-world property, consisting in e...

Bayesian Learning of Loglinear Models for Neural Connectivity

Authors: Kathryn Blackmond Laskey, Laura Martignon

arXiv

This paper presents a Bayesian approach to learning the connectivity structure of a group of neurons from data on configuration frequencies. A major objective of the research is to provide statistica...

Fractal-driven distortion of resting state functional networks in fMRI: a simulation study

Authors: Wonsang You, Jörg Stadler

arXiv

Fractals are self-similar and scale-invariant patterns found ubiquitously in nature. A lot of evidences implying fractal properties such as 1/f power spectrums have been also observed in resting state...

Survival analysis, the infinite Gaussian mixture model, FDG-PET and non-imaging data in the prediction of progression from mild cognitive impairment

Authors: Rui Li, Robert Perneczky, Alexander Drzezga, Stefan Kramer

arXiv

We present a method to discover interesting brain regions in [18F] fluorodeoxyglucose positron emission tomography (PET) scans, showing also the benefits when PET scans are in combined use with non-im...

Stability and Localization of inter-individual differences in functional connectivity

Authors: Raag D. Airan, Joshua T. Vogelstein, Jay J. Pillai, Brian Caffo, James J. Pekar, Haris I. Sair

arXiv

Much recent attention has been paid to quantifying anatomic and functional neuroimaging on the individual subject level. For optimal individual subject characterization, specific acquisition and analy...

Hemodynamically informed parcellation of cerebral FMRI data

Authors: Aina Frau-Pascual, Thomas Vincent, Florence Forbes, Philippe Ciuciu

arXiv

Standard detection of evoked brain activity in functional MRI (fMRI) relies on a fixed and known shape of the impulse response of the neurovascular coupling, namely the hemodynamic response function (...

A hierarchical narrative framework for OCD

Authors: P. J. Moore

arXiv

This paper gives an explanatory framework for obsessive-compulsive disorder (OCD) based on a generative model of cognition. The framework is constructed using the new concept of a 'formal narrative' w...

Studying the brain from adolescence to adulthood through sparse multi-view matrix factorisations

Authors: Zi Wang, Vyacheslav Karolis, Chiara Nosarti, Giovanni Montana

arXiv

Men and women differ in specific cognitive abilities and in the expression of several neuropsychiatric conditions. Such findings could be attributed to sex hormones, brain differences, as well as a nu...

The Same Analysis Approach: Practical protection against the pitfalls of novel neuroimaging analysis methods

Authors: Kai Görgen, Martin N. Hebart, Carsten Allefeld, John-Dylan Haynes

arXiv

Standard neuroimaging data analysis based on traditional principles of experimental design, modelling, and statistical inference is increasingly complemented by novel analysis methods, driven e.g. by...

GSplit LBI: Taming the Procedural Bias in Neuroimaging for Disease Prediction

Authors: Xinwei Sun, Lingjing Hu, Yuan Yao, Yizhou Wang

arXiv

In voxel-based neuroimage analysis, lesion features have been the main focus in disease prediction due to their interpretability with respect to the related diseases. However, we observe that there ex...
