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.

Related Experiment Videos

  • 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.
