In the article “Conditional Associative Memory for Musical Stimuli in Nonmusicians: Implications for Absolute Pitch,” by Patrick Bermudez and Robert J. Zatorre, which appeared on pages 7718–7723 of the August 24, 2005 issue, the most recent versions of Figures 2 and 4 were not used because of a printer's error. The correct versions of both figures, as well as each corresponding legend, are printed here.
S2chords – noise – S1chords – noise contrast. The sagittal cuts to the left of the figure indicate the location of the coronal cuts to the right. a, Inferior portion of the left middle frontal gyrus, near the rostral border of area 8 and partly in the inferior frontal sulcus. b, c, A band of activity along area 8 of the right middle frontal gyrus. d, The junction of the right posterior middle frontal gyrus and superior precentral sulcus, corresponding to rostral area 6/caudal 8.
a, Spatial conjunction of the tones – noise contrast in AP subjects from the PET results of Zatorre et al. (1998) and the S2chords – noise – S1chords – noise contrast of this study. b, Same as a but with the S2chords – noise – S1chords – noise image flipped at approximately the midsagittal line (see Results, Imaging: conjunction).
