Many cognitive paradigms require self-paced responses or examine events that occur at unpredictable times. To explore whether functional MRI (fMRI) can accommodate such paradigms, a method allowing rapid, unpredictable trial pacing was developed and tested on 17 subjects using activation of the motor network as a model. Trial onset was determined solely by the subjects' self-paced responses and...

How quickly can information about the neural response to a visual stimulus be detected in the hemodynamic response measured using fMRI? Multi-voxel pattern analysis (MVPA) uses pattern classification to detect subtle stimulus-specific information from patterns of responses among voxels, including information that cannot be detected in the average response across a given brain region. Here we us...
