The “slice” would be perpendicular to the groove between the hemispheres, towards the front half of the temporal lobe. Purple-blue is grey matter (cortex, various nuclei). Orange is white matter (axons connecting one area of the brain with another). The temporal lobes are the lower bulges on either side. The frontal lobes are the bulges above. The white inverted triangle in the middle is the two lateral ventricles (full of spinal fluid) covered by the (orange) connection between the two hemispheres (corpus callosum). The area of the cingulate gyrus and the area of the amygdala are labelled. So is the insula, the cortical region involved with the sense of taste and with disgust and nausea.
