Machine Learning for Neuroimaging with Scikit-Learn [PDF]

open access: yes, 2013
Statistical machine learning methods are increasingly used for neuroimaging data analysis. Their main virtue is their ability to model high-dimensional datasets, e.g. multivariate analysis of activation images or resting-state time series.

Disease state prediction from resting state functional connectivity [PDF]

open access: yesMagnetic Resonance in Medicine, 2009
AbstractThe application of multivoxel pattern analysis methods has attracted increasing attention, particularly for brain state prediction and real‐time functional MRI applications. Support vector classification is the most popular of these techniques, owing to reports that it has better prediction accuracy and is less sensitive to noise.

Prominent Changes in Cerebro-Cerebellar Functional Connectivity During Continuous Cognitive Processing

open access: yesFrontiers in Cellular Neuroscience, 2018
While task-dependent responses of specific brain areas during cognitive tasks are well established, much less is known about the changes occurring in resting state networks (RSNs) in relation to continuous cognitive processing.

Association of resting-state theta–gamma coupling with selective visual attention in children with tic disorders

open access: yesFrontiers in Human Neuroscience, 2022
A tic disorder (TD) is a neurodevelopmental disorder characterized by tics, which are repetitive movements and/or vocalizations that occur due to aberrant sensory gating.

Domain-general Stroop Performance and Hemispheric Asymmetries: A Resting-state EEG Study [PDF]

open access: yes, 2017
The ability to suppress irrelevant information while executing a task or interference resistance is a function of pFC that is critical for successful goal-directed human behavior.

Pre- and post-therapy functional MRI connectivity in severe acute brain injury with suppression of consciousness: a comparative analysis to epilepsy features

open access: yesFrontiers in Neuroimaging
Severe acute brain injury (SABI) with suppressed consciousness is a major societal burden, with early prognosis being crucial for life-and-death treatment decisions.

Phenomenology of retained refractoriness: On semi-memristive discrete media

open access: yes, 2011
We study two-dimensional cellular automata, each cell takes three states: resting, excited and refractory. A resting cell excites if number of excited neighbours lies in a certain interval (excitation interval).

Episodic memory retrieval, parietal cortex, and the default mode network: Functional and topographic analyses [PDF]

open access: yes, 2011
The default mode network (DMN) is often considered a functionally homogeneous system that is broadly associated with internally directed cognition (e.g., episodic memory, theory of mind, self-evaluation).

Posture alters human resting-state

open access: yesCortex, 2014
Neuroimaging is ubiquitous; however, neuroimagers seldom investigate the putative impact of posture on brain activity. Whereas participants in most psychological experiments sit upright, many prominent neuroimaging techniques (e.g., functional magnetic resonance imaging (fMRI)) require participants to lie supine.

Vigilance Effects in Resting-State fMRI [PDF]

open access: yesFrontiers in Neuroscience, 2020
Measures of resting-state functional magnetic resonance imaging (rsfMRI) activity have been shown to be sensitive to cognitive function and disease state. However, there is growing evidence that variations in vigilance can lead to pronounced and spatially widespread differences in resting-state brain activity. Unless properly accounted for, differences
