Selective activation of limbic and paralimbic cortical areas in the rhesus macaque elicited by rhesus screams. (A) Lateral view of a rhesus monkey brain illustrates approximate locations of the activations shown in the sagittal sections in E and the coronal sections in F and G. (B–D) Mean (±SEM) rCBF for each acoustic condition for activations in VMPFC area 32 (B), amygdala (C), and hippocampus (D). Group analysis using a repeated measures ANOVA with planned comparisons revealed that screams yielded significantly greater activation than both nonbiological sounds and coos in VMPFC area 32 (B)(F = 18.825; P < 0.05 corrected), the amygdala (C)(F = 27.095; P < 0.005 corrected), and the hippocampus (D)(F = 30.263; P < 0.005 corrected). (E–G) Sagittal (E) and coronal (F and G) slices illustrate the location of enhanced activity for screams vs. coos and screams vs. nonbiological sounds in VMPFC area 32 (E), amygdala (F), and hippocampus (G) in each animal. P, posterior; A, anterior.
