There is provided a system and method for generating visual category reconstruction from electroencephalography (EEG) signals. The method includes: receiving scalp EEG signals; using a trained pattern classifier, determining pairwise discrimination of the EEG signals, the pattern classifier trained using a training set comprising EEG signals associated with a subject experiencing different known visual identities; determining discriminability estimates of the pairwise discrimination of the EEG signals by constructing a confusability matrix; generating a multidimensional visual representational space; determining visual features for each dimension of the visual representational space by determining weighted sums of image stimulus properties; identifying subspaces determined to be relevant for reconstruction; and reconstructing the visual appearance of a reconstruction target using estimated coordinates of the target and a summed linear combination of the visual features proportional with the coordinates of the target in the visual representational space.
