Recent advances in MRI technique such as the multiband sequence have made fast sampling available up to 100-200 ms TR for whole brain acquisition. However, its usefulness is limited because there is not found any significant functional changes needed to be sampled with that short TR. In this study, we challenged to detect task-induced fast signals with the ultra-high temporal resolution imaging with 100 Hz sampling rates.
