Abstract

This work analyses the statistical significant changes in the EEG signal after the supply of olfactory stimuli during simultaneous EEG/fMRI olfactory experiments. Different spectral parameters are evaluated including the spectral power in different EEG bands of interest and spectral morphology measures, such as median frequency or statistical complexity. Beta 2 spectral power increase in frontal, midline and parietal areas has been found to be very significant (p < 0.00000840) when an odorant of any type is supplied to a subject in this experiment. Also, this increase has been found to be more significant for trigeminal than for natural odorants.
