Fig 1.
Distributions of age (top-left), interest in painting arts (top-right), nationality (bottom-left) and education level (bottom-right) of the subjects.
Fig 2.
Example of a raw EEG signal of a single subject, from a single electrode; the first highlighted area corresponds to the blank portion of the observation, while the others correspond, each, to the observation of different paintings (here, only two paintings are shown in the picture).
Fig 3.
From top to bottom, the intensity of voltage at the band δ, θ, α, β (specifically, the interval of β included in F6), and γ bands (specifically, the interval of γ included in F11) during the trial of example in Fig 2, after preprocessing. All graphics are log10-normalized. As before, the first highlighted area corresponds to the blank portion of the observation, while the others correspond, each, to the observation of different paintings (again, only two paintings are shown in the picture).

Fig 5.
Selected electrodes and measures for the dataset corresponding to the 25-25 binning.
On the right-hand side, their spatial distribution (from dark to light: best one, best five, best ten), and on the left-hand side, top, their ordering. On the left-hand side, also, ordering of the best measures with the different selections (from line 2 to bottom: with the best ten measures, the best five, and with the best electrode only.)
Fig 6.
Selected electrodes and measures for the dataset corresponding to the 17-34 binning.
On the right-hand side, their spatial distribution (from dark to light: best one, best five, best ten), and on the left-hand side, top, their ordering. On the left-hand side, also, ordering of the best measures with the different selections (from line 2 to bottom: with the best ten measures, the best five, and with the best electrode only.)
Fig 7.
Selected electrodes and measures for the dataset corresponding to the 10-41 binning.
On the right-hand side, their spatial distribution (from dark to light: best one, best five, best ten), and on the left-hand side, top, their ordering. On the left-hand side, also, ordering of the best measures with the different selections (from line 2 to bottom: with the best ten measures, the best five, and with the best electrode only.)
