Event-related_potential_datasets_based_on_three-stimulus-paradigm/Experiment_87_P3_LED_(D,T,N)/Data

The data were stored in BrainVision Format. The following stimuli were used:

-> T � Target stimulus
-> N � Non-Target stimulus
-> D � Distractor stimulus

The following files were stored:


Data files:
-> LED_DD_MM_YYYY_EXP-ID.eeg - a binary file containing raw data


-> LED_DD_MM_YYYY_EXP-ID-T.avg - a binary file containing averaged raw data related to the marker "T" (i.e. epochs)
-> LED_DD_MM_YYYY_EXP-ID-N.avg - a binary file containing averaged raw data related to the marker "N" (i.e. epochs)
-> LED_DD_MM_YYYY_EXP-ID-D.avg - a binary file containing averaged raw data related to the marker "D" (i.e. epochs)


Header files:
-> LED_DD_MM_YYYY_EXP-ID.vhdr - a text file containing metadata describing raw data in the .eeg file
-> LED_DD_MM_YYYY_EXP-ID-T.vhdr - a text file containing metadata describing raw data in the .eeg file related to the marker "T"
-> LED_DD_MM_YYYY_EXP-ID-N.vhdr - a text file containing metadata describing raw data in the .eeg file related to the marker "N"
-> LED_DD_MM_YYYY_EXP-ID-D.vhdr - a text file containing metadata describing raw data in the .eeg file related to the marker "D"

-> LED_DD_MM_YYYY_EXP-ID.vmrk - a text file containing markers used in the experiment
-> LED_DD_MM_YYYY_EXP-ID-T.vmrk - a text file containing markers used in the experiment related to the marker "T"
-> LED_DD_MM_YYYY_EXP-ID-N.vmrk - a text file containing markers used in the experiment related to the marker "N"
-> LED_DD_MM_YYYY_EXP-ID-D.vmrk - a text file containing markers used in the experiment related to the marker "D"


Recording Software
For recording and storing the EEG/ERP data, the BrainVision Recorder 1.2 was used. The Recorder was initialized using the following parameters:

1) the sampling rate was set to 1 kHz
2) the number of channels was set to 19
3) the resolution was set to 0.1 �V
4) a low-pass filter was set with the cut-off frequency of 250 Hz
