Validation of statistical methods used in task fMRI studies
Functional Magnetic Resonance Imaging (fMRI) is a non-invasive tool used to investigate brain function. The processing of fMRI data consists of multiple steps and the final results often depend greatly on the specific choice of options used: for example, head motion correction, slice timing …

Statistical methods for fMRI data analysis
Since the early 1990s, functional magnetic resonance imaging (fMRI) has dominated the brain mapping field and it has been proved a powerful tool for mapping human brain functions. The fMRI is a high spatial-temporal resolution medical-imaging modality, which means the data structure is complicated …

Detection power, temporal response, and spatial resolution of IRON fMRI in awake, behaving monkeys at 3 Tesla
… characterize the detection sensitivity, temporal response, and spatial resolution of IRON contrast for fMRI within the awake, behaving monkey. Understanding these issues provides insights into the physiology of the functional response to local changes in brain activity, enables researchers to …

Characterization of mismatch between behavioral stimuli and FRMI data using the Kalman filter
The advance of blood oxygen level dependent function magnetic resonance imaging, (BOLD fMRI), allows researchers to non-invasively investigate the functioning human brain. The BOLD fMRI response to brief stimuli is called the hemodynamic response function (HRF), which can vary across brain regions …

Identifying the Neural Correlates of Motor Sequence Learning and Movement Automaticity
… such as movement automaticity, stimulus-response conflicts, explicit learning, and retrieval, to name a few. However, it is difficult for neuroimaging studies to evaluate the relative permanence of motor sequence learning due to the financial burden associated with functional magnetic …
