Description

The data were originally collected for the paper "Olfactory Response as a Marker for Alzheimer’s Disease: Evidence from Perception and Frontal Oscillation Coherence Deficit" in Ziaeian Hospital, Tehran, Iran. The study was conducted on mild AD and normal participants. This data includes EEG from 4 channels (Fp1-Fz-Cz-Pz) with A1 earlobe as reference. The sampling frequency is 200 Hz. It contains EEG segments during olfaction of two odors (Lemon and Rosewater). Each segment contains 1 second before and 2 seconds after the stimulus onset. Segments corresponding to Lemon odor are indicated by 0 and Rosewater segments are denoted by 1 in a vector inside the dataset. In addition, noisy epoch numbers are included in the dataset. The order of the channels in the dataset is as follows: Fp1 - Fz - Cz - Pz. The data is preprocessed and eye-blink artifact was removed using FastICA algorithm. Data on Iran-SIT score as well as participants' MMSE scores can be found in .xlsx file. If you used this data and found it helpful, please cite our paper.
