Comparison of 3D default space consciousness model and other current models.
| Questions addressed by consciousness models: | Integrated information theory | Global workspace theory | 3D default space theory |
|---|---|---|---|
| Does it involve a global theory involving brain and body? | Yes | Yes | Yes |
| Does corticothalamic activity play a major role? | Yes | Yes | Yes |
| Does it address underlying physiology? | No | Yes, partially | Yes |
| Is it an expandable model? (Can it be integrated with other models?) | Limited expandability | Limited expandability | Yes |
| Can the model be visualized via illustrations? | No | No | Yes |
| Does the model address emotions? | Yes, partially | Yes, partially | Yes |
| Does it address cardiorespiratory coherence? | No | No | Yes |
| Does it address the role of breathing on various rhythms including the brain? | No | No | Yes |
| Does it address the role of homeostasis and membrane potential changes? | No | No | Yes |
| Is the thalamus a central hub for consciousness in the model? | No | No | Yes |
| How is consciousness perceived? | Externally | Externally | Internally |
| Does the model explain the self? | No | No | Not at present |
| Does the model explain how of visual and other sensory inputs are integrated? | Yes | No | Yes |
| Can the model illustrate the etiological deficits of the following disorders: | |||
| a) Contralateral neglect syndrome | No | No | Yes |
| b) Phantom limb | No | No | Yes |
| c) Motion sickness | No | No | Yes |
| d) Vertigo | No | No | Yes |
| e) Claustrophobia | No | No | Yes |
| Can the model explain anxiety vs. mind-body response and the involved underlying physiology? | No | No | Yes |
| Does the model address how emotions and sensory info is integrated? | No | No | Yes |
| Does the model have experimental evidence? | Partial | Partial | Partial |
| Does the model include the autonomic nervous system? | No | No | Yes |
| Limitations of these consciousness models: | |||
| a) Does it identify spatiotemporal coordinates of emotions? | No | No | No |
| b) Does it detail the link between neural oscillations and visual and auditory consciousness? | No | No | No |
| c) Can the model explain the relationship of body movement to 3D default space? | N/A | N/A | No |
Green indicates that the consciousness model addresses the corresponding question while red indicates that the model does not address the question.
