Paradigm design diagram showing checkerboard pattern used and the visual stimulus PR (top row), this is convolved with the canonical hemodynamic response function (second row) to form a model of expected signal changes. Based on the sequence parameters these signal changes are sampled at different rates (bottom 4 rows). TR is the repetition rate in milliseconds, FA is the flip angle, vols is the number of imaging volumes
