Data for Olfactory Function of Chinese PD Patients: an Event Related fMRI Study

Hyposmia is one of the early signs in idiopathic Parkinson’s disease (PD). Olfactory stimuli were applied during fMRI scanning to show disease-related modulation of central nervous system structures and to advance our understanding of olfactory dysfunction in PD patients. Although there are a few fMRI studies on hyposmia, the findings are inclusive. Therefore, Using a block design of at a 3.0 T scanner we investigated a total of 19 PD patients and 20 age matched controls, while passively perceiving a positively valenced (rose-like or lavender) odoran .Th edifferent activated brain region are also observed.
