Investigating the Triple Code Model in numerical cognition using stereotactic electroencephalography
Fig 8
Linear SVM classification of spectrograms from all assorted dots trials versus inter-trial interval spectrograms.
Classification values of parcellated cortical and subcortical brain regions are presented with a gradient (Yellow; 1 = 100% classification accuracy, Purple: 0.68 = 68% classification accuracy) (A). The three contacts with the highest classification value are shown in (B). Left panels show SVM coefficients from the spectrogram classification projected back to spectrogram space using the principal components with significant clusters shown by the red contours. Right panels show the location of the contact within parcellated brain regions.
