Subject 1 (Female) -> 1 Day --> 15 sessions
Subject 2 (Male) -> 1 Day --> 20 sessions
Subject 3 (Female) -> 1 Day --> 20 sessions
Subject 4 (Female) -> 1 Day --> 20 sessions
Subject 5 (Male) -> 3 Day --> Day 1: 18 sessions / Day 2: 20 sessions
/
Day 3: 20 sessions
Each session consists of 14 trials, and of each figure there are 2 trials per session (2 * 7 = 14 trials).
The registration protocol has been carried out through OpenVibe, with two .csv files:
-a file called "eeg # number.csv" containing the EEG signal,
for example "eeg01.csv"
-and another called "estimulos # number.csv" stimuli containing
the events have been generated for each session,
for example "estimulos01.csv"
The registration protocol is as follows: :
During the first second a white arrow appears on a black background indicating
the start of the trial, during the next two seconds the figure that the person
must imagine appears, the figure appears in white on a black background, then
the person imagines for six seconds the indicated figure. Channels used:
The channels used
using the 10/20 notation are:
The correspondence of the channels on the file are as follows:
Channel 1 -> Oz
Channel 2 -> P3
Channel 3 -> POz
Channel 4 -> P4
Channel 5 -> PO7
Channel 6 -> PO4
Channel 7 -> PO3
Channel 8 -> PO8
Correspondence between events
number and geometric shapes :
33025 -> Triangle
33026 -> Circle
33027 -> Square
33028 -> Pentagon
33029 -> Straight line
33030 -> Hexagon
33031 -> Parallelogram
