Relationship between MBEA scores and MMNm responses 1 week after the stroke.

Scatterplots indicating the correlation between the MBEA average score and the duration and frequency MMNm overall amplitudes (average of left and right hemisphere responses) are shown for non-amusic patients (n = 21), amusic patients with left hemisphere damage (LHD amusic, n = 12) and amusic patients with right hemisphere damage (RHD amusic, n = 20). Regression lines are shown only for statistically significant correlations. The dashed line in the upper figure is for all patients (n = 53) and the solid line in the lower figure is for RHD amusic patients.
