Multisubject, Multimodal Demo Dataset: Neuroimaging Analysis of Face Perception

This dataset consists of neuroimaging data from 16 subjects who participated in two experiments involving MEG and EEG, as well as fMRI and MRI. The dataset includes EEG recordings with 70 channels, MEG recordings with 102 magnetometers and 204 planar gradiometers, fMRI data using BOLD EPI, and T1 MRI scans. The dataset also includes raw stimuli, processing scripts, and incomplete data from 5 additional subjects. The experiments involved judging left-right symmetry of famous, unfamiliar, and phase-scrambled grayscale faces. The dataset is available for analysis and is accompanied by example scripts.

MEG + EEG 2. fMRI + MRI EEG = 70 channels, nose-reference (concurrent with MEG) MEG = 102 magnetometers + 204 planar gradiometers (Neuromag) fMRI = BOLD EPI 3x3x3 (3T Siemens Trio) MRI = T1 MPRAGE 1x1x1 (Also available: DTI data on 11 of the 16 subjects FLASH data on all 16 subjects (head modelling)) Empty-room MEG datasets Raw stimuli and processing scripts Extra 5 subjects with incomplete data) Each experiment had 3 types of grayscale faces: Famous Unfamiliar (previously unseen) Phase-scrambled versions of above 300 trials of each (ie 900 in total, split across 6 (MEEG) or 9 (fMRI) runs) Subjects judged left-right symmetry of each (Soon to be a chapter in SPM12 manual, together with example scripts)
