Improved Activation and Hemodynamic Response Function of Olfactory fMRI Using Simultaneous Multislice with Reduced TR Acquisition

Figure 1

Odor stimulation paradigm. Three different concentrations of lavender: low (0.10%), medium (0.33%), and high (1.00%), are presented. Each concentration is repeated five times before the next higher concentration. Each odor stimulus is 6 s. The interstimulus interval is 36 s with odorless air. Olfactory task is initiated with a 36 s odorless air. The total time of olfactory task is 666 s.
