Table 2.

Cerebral areas of differential response to positive versus negative vocalizations. (Peaks of significant (p<0.001 uncorrected) BOLD signal difference between positively and negatively valenced vocalizations are listed with approximate anatomical localization, coordinates in Talairach space and t-value of peak. ^*p<0.005 uncorrected in the conjunction analysis.)
