Summary
This study presents a neurocognitive model defining consciousness as a global integration and dissemination system. This system, controlled by cortical gating of a thalamic nucleus, manages central nervous system processing resources.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Artificial Intelligence
Background:
- Progress in developing a general theory of the neural correlates of consciousness.
- Baars' Global Workspace theory as a key development.
Purpose of the Study:
- To present an integrated neurocognitive model of consciousness.
- To define consciousness as a global integration and dissemination system.
Main Methods:
- Integrating experimental data and models from cognitive psychology, AI, and neuroscience.
- Modeling the neural system using neural network principles.
Main Results:
- Consciousness is modeled as a global integration and dissemination system.
- This system controls central nervous system processing resource allocation.
- Cortical gating of a strategic thalamic nucleus is proposed as the control mechanism.
Conclusions:
- The proposed neurocognitive model offers a framework for understanding consciousness.
- The basic circuitry of the neural system is understood and modelable.
