Table 1: The absolute values of the pair-wise Pearson correlation coefficients \(|\rho|\) corresponding to the associated triplets and the values of \(p_{\rho}\). right brain hemispheres and allows communications of sensory, motor, and cognitive information between the two hemispheres. The STG is a cortical area responsible for auditory processing, multisensory integration, and spoken word recognition. The PCL is important for motor functions, while the POG is the location of the primary somatosensory cortex, which is responsible for the sense of touch. Thus, this triplet primarily focuses on sensory functions. The third triplet includes the corticospinal tract and superior longitudinal fasciculus (CST-SLF), uncus and inferior temporal gyrus (Uncus-ITG), and superior frontal gyrus and middle frontal gyrus (SFG-MFG) from dMRI, sMRI, and fMRI, respectively. The CST is a fiber tract that originates from the motor-related cerebral cortex to the motor neurons and interneurons in the spinal cord and controls body movement. The SLF is a fiber tract that connects frontal, occipital, parietal, and temporal lobes including the premotor cortex, thus playing a role in regulating cognitive functions and motor behavior. The ITG is the anterior region of the temporal lobe, which is important for object cognition and memory. SFG and MFG occupy a large proportion of the frontal area that is also involved in cognition and motor functions. The three ICs within this triplet all show significant group differences between the HCs and SZs, suggesting that the structural and functional changes in these brain cognition and motor networks might be related to the cognitive dysfunction and motor deficits in SZs, thus revealing a multimodal neuroimaging biomarker of SZ. The fourth triplet includes the superior longitudinal fasciculus (SLF), middle occipital gyrus and fusiform gyrus (MOG-FG), and cuneus and middle occipital gyrus (Cuneus-MOG) from dMRI, sMRI, and fMRI, respectively. The FG a large gyrus that spans across the temporal and occipital lobes. Both MOG and FG are involved in visual processing and cognition. Besides, the SLF is a fiber tract that connects to brain regions that are involved in cognitive function. Thus, this triplet might primarily process visual cognition such as object and facial recognition. The fifth triplet includes CST-SLF, Precuneus-PCL, and STG from dMRI, sMRI, and fMRI, respectively. While both the structural components are involved in motor functions, the functional component is involved in sensory processing, representing a sensory-motor network across the three modalities. The sixth triplet includes SCR-CST, POG-PCG, and culmen from dMRI, sMRI, and fMRI, respectively. The three components are all related to motor function. As we can see from the description of the six triplets, all triplets represent networks that are involved, at least partially, in motor functions, and many are related to cognitive functions.
