Magnetoencephalography was recorded while four participants viewed and discriminated among 91 face identities. For each participant, the data set includes MEG recordings for each block of the task and for an independent localizer task. It also includes MRI recordings for source modeling of MEG signals, and behavioral data from the MEG face identity task. Also included are pairwise behavioral similarity ratings of a subset of the stimuli from 7 participants who did not participate in the main MEG experiment.
