Two attentional systems: Corbetta and Shulman, 2002
- Endogenous systems - goal directed/top down processing. The voluntary system selects sensory information according to personal goals, knowledge and expectations. This uses the frontoparietal network.
- Exogenous systems - stimulus-driven/bottom up processing. This is used when a salient, unexpected visual stimulus is presented. The involuntary system selects the unattended stimuli as 'circuit breaking' redirects attention. This process involves the right hemisphere in the ventral frontoparietal network
