Enhanced design matrix for task-related fMRI data analysis

•A novel methodology to enhance the standard design matrix is proposed within the GLM framework for task-related fMRI data analysis.•The proposed methodology offers an enhanced potential: (a) It efficiently copes with uncertainties in modeling the hemodynamic response. (b) It accommodates unmodeled...
