AgCC Brain Activity (IMAGE) California Institute of Technology Caption Top image: Magnetic resonance images comparing a healthy subject (left) with an AgCC patient (right). The corpus callosum is the thick, "c"-shaped structure outlined in the healthy brain and missing from the AgCC brain. Bottom image: Functional magnetic resonance images highlight symmetric patterns of synchronized activity in both healthy (left) and AgCC subjects (right) during rest with eyes closed. More than 15 of this type of network were found to be preserved in AgCC subjects. Credit California Institute of Technology Usage Restrictions Okay with credit.
