Social Cognitive Deficits

The corpus callosum is a thick band of white matter which literally connects both sides of the brain and allows for communication between the two hemispheres (right brain/left brain). The corpus callosum is the most sensitive area of the brain to high velocity changes as in a car accident. Adults with severe chronic TBI underwent MRI/DTI testing of the corpus callosum and performed on the awareness of social inference test (TASIT)which showed a strong correlation between injury to that area and test scores on social awareness. Again, confirming that TBI caused severe social disabilities.
