Non-parametric Hemodynamic Response Function (HRF) estimation in noisy functional Magnetic Resonance Imaging (fMRI) plays an important role when investigating the temporal dynamics of regional brain responses during activation. Making use of a semiparametric model to characterize the fMRI time series and a sparsity assumption on the HRF, a new method for voxelwise non-parametric HRF estimation is...
Discriminating between active and non-active brain voxels in noisy functional magnetic resonance imaging (fMRI) data plays an important role when investigating task-related activations of the neuronal sites. A novel method for efficiently capturing drifts in the functional magnetic resonance imaging (fMRI) data is presented that leads to enhanced fMRI activation detection. The proposed algorithm apply...
Extracting region-specific hemodynamic response function (HRF) from overlapping ROIs of activated areas in the brain in noisy functional Magnetic Resonance Imaging (fMRI) data is essential when analyzing the temporal dynamics of a brain region response and its neuronal coupling for functional and effective connectivity. Based on the assumption of spatially sparse brain hemodynamics, HRFs from jointly...
