The purpose of this work was to test the ultrafast fMRI sequences for the study of the sensorimotor and cognitive functions of the human brain. In a series of test tasks for performing motor movements, the obtained fMRI data showed similar results of brain activity for the block paradigm with standard sequences (TR = 2000 ms) and ultrafast (TR = 300 ms) and event-related paradigm with the use of ultra-fast sequences. In the emotional task, fMRI data was performed in three scan modes: TR=2000 ms, TR=1000 ms, TR=700 ms. The obtained data show the promise of using in cognitive studies of ultrafast sequences, which opens up fundamentally new opportunities for fully non-invasive visualization of networks in the brain.
