Causal effect of disconnection lesions on interhemispheric functional connectivity in rhesus monkeys

Our new paper just came out in PNAS: O’Reilly Croxson et al. Causal effect of disconnection lesions on interhemispheric functional connectivity in rhesus monkeys.

Screen Shot 2013-08-07 at 16.15.39Sectioning the corpus callosum in monkeys leads to breakdown in functional connectivity between the hemispheres. However, when the anterior commissure is left intact, a surprising amount of functional connectivity between the hemispheres remains. The relationship between cortico-cortical structural connections and functional connectivity is not as simple as we once thought.
