a Receptive fields corresponding to the six most negative eigenvalues for a single electrode whose delta power response was fit with purely spectrographic information. b Receptive fields of the six most positive eigenvalues for the same electrode as (a). c Left: Eigenvalues of the fit model, ordered by their value. Gray shaded box encompasses the bottom 95% of eigenvalue magnitudes. Right: The power-dependent average receptive field. d Receptive fields for the six most negative eigenvalues reconstructed from the delta power response of the same electrode shown in (a) using a model that was fit with both spectrographic and phonemic label information. e Receptive fields of the six most positive eigenvalues for the same electrode as (d). f Left: Eigenvalues of the fit model, ordered by their value. Gray shaded box encompasses the bottom 95% of eigenvalue magnitudes. Right: The power-dependent average receptive field.
