Researchers explored neural network features in cortical processing to bridge the explanatory gap between consciousness and brain activity. They identified a specific neural processing style, cortical activity "bubbles," as a promising model for phenomenal consciousness.

Area of Science:

  • Neuroscience
  • Cognitive Science
  • Philosophy of Mind

Background:

  • The "Explanatory Gap" highlights the difficulty in linking subjective conscious experience to objective neural activity.
  • Understanding the neural basis of phenomenal consciousness remains a significant challenge in neuroscience.
  • Existing models struggle to account for the richness of conscious experience.

Purpose of the Study:

  • To explore neural network features that may bridge the explanatory gap.
  • To identify criteria for neural activity correlated with phenomenal consciousness.
  • To propose a neural model for consciousness based on specific processing styles.

Main Methods:

  • Surveying properties of phenomenal consciousness to establish criteria for neural correlates.

  • Reviewing various neural processing styles.
  • Selecting and analyzing neural processing styles that fit the established criteria.
  • Applying further experimental criteria to refine potential neural models.
  • Main Results:

    • Identification of semiautonomous, long-lasting cortical activity "bubbles" as a key processing style.
    • Development of a class of neural models that may underpin phenomenal consciousness.
    • Formulation of testable predictions derived from the proposed neural models.

    Conclusions:

    • Cortical activity "bubbles" offer a potential neural mechanism for aspects of phenomenal consciousness.
    • The proposed neural models provide a framework for future empirical investigation.
    • Bridging the explanatory gap requires integrating insights from neuroscience, cognitive science, and philosophy.
