Functional MRI results
Functional data of the sniffing paradigm was submitted for a first and second level analysis using SPM MATLAB toolbox for both the healthy controls and the patient group. fMRI analysis of healthy controls revealed a significant number of areas that were activated during olfactory stimulation (Table 4). Significant differences in activation areas were determined between the healthy control group and the patient group after performing a two-sample T-test (Fig 3).
