A-L. Monkey M. M-P. Monkey Y. A-B. Stimulation site in intermediate zone of the basal nucleus. C-D. Schematics of cortical areas in the lateral sulcus, including insular cortical areas. insula: lg, ld, Ri. Auditory areas: AI, CM, ML, R, RM. Somatosensory areas: SII, 1–2. (Saleem and Logothetis, 2012) E-H. Activations within the lateral sulcus from posterior (+9.5) to anterior (+17) (9.5 mm, 11 mm, 12,5 mm,17 mm, respectively). Voxels: p < 0.0001 (FDR 5.5%). Black box: approximate regions shown in C-D. I-L: Associated time courses of fMRI signal in E-H (mean of significant voxels). Inset: enlarged schematic of each stimulus train (red line). Stimulation: block design, 0.1 J/cm2. Error bars: SEM. M-P. Activations within the lateral sulcus are seen in monkey Y. Voxels: p < 0.001.
