A typical time series of an activated pixel in primary cortex is shown to represent the performance of horizontal 3 T system optimized for fMRI. S/N indicated variation of EPI images, while _I, activation induced increase in signal intensity. This time series represents signals from a single voxel volume of 3 mm × 3 mm × 5 mm. The red curves represent raw data and boxcar type model functions shown in blue color.
