Description:
This EEG dataset contains data for 11 participants numbered 2-7 and 9-13. Each participant's folder has one Objects and one Meaningless Objects folder. Each of these folders has the hit trials from two blocks of recording. 

Pre-processing was accomplished using the Brainstorm toolbox:
Continuous raw EEG data were bandpass filtered (2-50Hz), downsampled to 1000Hz and re-referenced to common average. Data from channels A1 and A2 were removed for all participants. Eye blinks and eye movement artifacts were removed using SSP/ICA. The data was the epoched from -2 seconds to 4 seconds from the time of stimulus onset. Trials which had excessive muscle artefacts were removed by careful visual inspection. The trials from both the experimental blocks were then pooled together and those with correct responses (hit trials) were categorized into 'objects' and 'meaningless-objects' datasets for each participant.
