Hippocampal sclerosis affects fMR-adaptation of lyrics and melodies in songs [PDF]
, 2013 Songs constitute a natural combination of lyrics and melodies, but it is unclear whether and how these two song components are integrated during the emergence of a memory trace.

Multiscale adaptive smoothing models for the hemodynamic response function in fMRI [PDF]
, 2013 In the event-related functional magnetic resonance imaging (fMRI) data analysis, there is an extensive interest in accurately and robustly estimating the hemodynamic response function (HRF) and its associated statistics (e.g., the magnitude and duration ...

The relationship between fMRI adaptation and repetition priming
NeuroImage, 2006 Neuroimaging investigations of the cortically defined fMRI adaptation effect and of the behaviorally defined repetition priming effect have provided useful insights into how visual information is perceived and stored in the brain. Yet, although both phenomena are typically associated with reduced activation in visually responsive brain regions as a ...

S3-3: Misbinding of Color and Motion in Human V2 Revealed by Color-Contingent Motion Adaptation
i-Perception, 2012 Wu, Kanai, & Shimojo (2004 Nature 429 262) described a compelling illusion demonstrating a steady-state misbinding of color and motion. Here, we took advantage of the illusion and performed psychophysical and fMRI adaptation experiments to explore the ...

Stages of nonsymbolic number processing in occipitoparietal cortex disentangled by fMRI adaptation [PDF]
, 2011 The neurobiological mechanisms of nonsymbolic number processing in humans are still unclear. Computational modeling proposed three successive stages: first, the spatial location of objects is stored in an object location map; second, this information is ...

A Functional Neuroimaging Analysis of the Trail Making Test-B: Implications for Clinical Application
Behavioural Neurology, 2011 Recent progress has been made using fMRI as a clinical assessment tool, often employing analogues of traditional “paper and pencil” tests. The Trail Making Test (TMT), popular for years as a neuropsychological exam, has been largely ignored in the realm ...

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.
