Functional activation 3D maps of left and right brain obtained for the novel (a), target (b), and target-novel contrast (c). (a) Brain regions showing activity to the novel stimuli. (b) Brain regions showing activity to the target stimuli. (c) Brain regions showing activity to the novel-target contrast. Reported activation became all thresholds at uncorrected. Gray reflects the background baseline state of the cerebral cortex; the darker the color, the closer to orange-red, indicating that the increased rate of blood oxygen concentration in the brain area is more significant, indicating that the area is being activated. The lighter the color, the closer to blue, which means that the rate of decrease in blood oxygen concentration in this brain area is more significant, indicating that this area is negatively activated. a1: in the new heterostimulus task state, the activation area of the left brain 3D model; a2: in the new heterostimulus task state, the activation area of the 2D model of the left cerebral cortex; a3: in the new heterostimulus task state, the activation area of the right brain 3D model; a4: in the new heterostimulus task state, the activation area of the 2D model of the right cerebral cortex; b1: in the target stimulation task state, the activation area of the left brain 3D model; b2: in the target stimulation task state, the activation area of the 2D model of the left cerebral cortex expanded; b3: in the target stimulation task state, the activation area of the right brain 3D model; b4: in the target stimulation task state, the activation area of the 2D model of the right cerebral cortex; c1: for fMRI image data, using target stimulation-new stimulation, the activation area of the left brain 3D model; c2: for fMRI image data, using target stimulation-differential stimulation, the activation area of the 2D model of the left cerebral cortex; c3: for fMRI image data, use target stimulation-new stimulation, the activation area of the right brain 3D model; c4: for fMRI image data, using target stimulation-differential stimulation, the activation area of the 2D model of the right cerebral cortex.
