  1. TR repetition time; TE echo time; TI inversion time; MPRAGE magnetization-prepared 180 degrees radio-frequency pulses and rapid gradient-echo; fMRI functional magnetic resonance imaging; HYFA imaginary straight line from the ventral hypophysis to the fastigium in the roof of the fourth ventricle.
  2. a Number of volumes for task-based fMRI varies because the scan is manually stopped around 3 s after the end of the task
