Figure 3: Comparison of the effects of aSTP and aSTS stimulation in Monkey 1.
From: Different forms of effective connectivity in primate frontotemporal pathways
(a) Significantly activated clusters (cluster corrected P<0.05) in Macaque 1 (M1) resulting from stimulating the voice-sensitive cluster in the aSTP (Supplementary Fig. 1; crosshairs identify site of stimulation). Results are shown on a surface-rendered macaque template brain (gyri, light grey; sulci, dark grey). (b) Significantly activated clusters resulting from aSTS microstimulation. (c) Analytical contrast between the effects of stimulating the aSTS versus aSTP sites. Bar graphs show the results of anatomically defined ROI analyses (shown is the ROI mean voxel z score, ±s.e.m., across trials). The results show that the OFC ROI is consistently more activated by aSTS than by aSTP stimulation (Supplementary Table 1 summarizes the anatomical regions activated). No significantly activated voxels were observed in the contralateral (right) hemisphere.
