Object recognition in healthy aging (ORHA) - EEG

This dataset contains the raw EEG data accompanying the paper "Healthy aging delays and dedifferentiates high-level visual representations". Please cite the above paper if you use this data.

The dataset includes:

Brainvision files (.eeg, .vhdr, .vmrk) for all participants.

The events files contain the onsets, durations, trial types and values for all trials in the corresponding run. Stimuli are images presented on a grey background with a central fixation:

images of faces = S1-16
images of animals = S17-32
images of places = S33-48
images of objects = S49-64
catch trials = S65-69

Other triggers:

button_press = S99
run_onset = S100+run_number (8 runs in total)
run_end = S199

For a full description of the paradigm and the employed procedures please see the paper.
