Model 1. Reticular activating system |
Maintains vigilance and arousal |
|
Model 1. Cingulate |
Imparts motivational significance to information |
|
Model 1. The posterior parietal region |
Provides sensory map of the world |
|
Model 1. The frontal regions |
Provides motor programs for moving the focus of attention |
|
Subsystem model: locus coeruleus, parietal cortex, right frontal regions |
Supports alertness |
|
Subsystem model: superior colliculus, superior parietal region, temporal-parietal junction and frontal eye fields |
Allows attention to be oriented to sensory signals to select among them |
|
Subsystem model: basal ganglia, lateral ventral prefrontal region and anterior cingulate cortex |
Supports executive aspects of attention |
|
Model 3. Dorsal frontoparietal subsystem |
involved in executive aspects of attention |
|
Model 3. Ventral subsystem (temporoparietal cortex and inferior frontal cortex of right hemisphere) |
Allows attention to be directed to salient stimuli in the environment |
|
Default network |
Whose activity is decreased when individual are engaged in an attentionally demanding task. |
