Action selection in multi-effector decision making

► fMRI study comparing single effector and coordinated multi-effector decision making. ► We find effector-specific value signals in supplementary motor and cingulate cortex. ► Value signals in prefrontal cortex (PFC) show no evident effector-specific structure. ► Connectivity between PFC and cingulate increases in multi-effector actions. ► Suggests multi-effector choices involve top-down control from abstract valuations.
