Adaptive thresholding for fMRI data
, 2011 In the analysis of functional MRI-data, several thresholding procedures are available to account for the huge number of volume units or features that are tested simultaneously. The main focus of these methods is to prevent an inflation of false positives.

Spatially Adaptive Mixture Modeling for Analysis of fMRI Time Series [PDF]
IEEE Transactions on Medical Imaging, 2009 Within-subject analysis in fMRI essentially addresses two problems, the detection of brain regions eliciting evoked activity and the estimation of the underlying dynamics. In Makni et aL, 2005 and Makni et aL, 2008, a detection-estimation framework has been proposed to tackle these problems jointly, since they are connected to one another.

fMRI Adaptation: Stimulus Specific or Processing Load Specific? [PDF]
The Journal of Neuroscience, 2007 Repetition suppression, or fMRI-adaptation, refers to decreased neural activity for repeated versus novel stimuli as measured with functional magnetic resonance imaging (fMRI). Recently, this technique has been widely used, especially in probing the plasticity of the nervous system and ...

Reading positional codes with fMRI: Problems and solutions.
PLoS ONE, 2017 Neural mechanisms which bind items into sequences have been investigated in a large body of research in animal neurophysiology and human neuroimaging. However, a major problem in interpreting this data arises from a fact that several unrelated processes,

, 2018 Previous work has demonstrated that a region of the extrastriate visual cortex, the left lateral occipito-temporal cortex, contains a region that is activated by both images of human hands and manual tools.

Adaptive experimental condition selection in event-related fMRI [PDF]
2012 9th IEEE International Symposium on Biomedical Imaging (ISBI), 2012 Standard Bayesian analysis of event-related functional Magnetic Resonance Imaging (fMRI) data usually assumes that all delivered stimuli possibly generate a BOLD response everywhere in the brain although activation is likely to be induced by only some of them in specific brain areas.

Residual fMRI sensitivity for identity changes in acquired prosopagnosia
Frontiers in Psychology, 2013 While a network of cortical regions contribute to face processing, the lesions in acquired prosopagnosia are highly variable, and likely result in different combinations of spared and affected regions of this network.

Functional Connectivity Signatures of Parkinson’s Disease
Journal of Parkinson’s Disease, 2019 Resting-state functional magnetic resonance imaging (RS-fMRI) studies have been extensively applied to analyze the pathophysiology of neurodegenerative disorders such as Parkinson’s disease (PD).

Identifying Autism Spectrum Disorder With Multi-Site fMRI via Low-Rank Domain Adaptation
IEEE Transactions on Medical Imaging, 2020 Autism spectrum disorder (ASD) is a neurodevelopmental disorder that is characterized by a wide range of symptoms. Identifying biomarkers for accurate diagnosis is crucial for early intervention of ASD.

The representation of material categories in the brain
Frontiers in Psychology, 2014 Using textures mapped onto virtual nonsense objects, it has recently been shown that early visual cortex plays an important role in processing material properties. Here, we examined brain activation to photographs of materials, consisting of wood, stone,
