    Brain activity relies on specialized nervous system connections, forming dynamic "interaction foci." These foci synthesize sensory, motivational, and memory information, enabling unique mental experiences and specialized cognitive functions.

    Area of Science:

    • Neuroscience
    • Cognitive Science
    • Brain Function

    Background:

    • Brain organization involves nervous integration, functional specialization, and adaptable connections.
    • Rigid connections stem from synaptic changes, while flexible connections arise from synchronized neural activity.
    • Dynamic structures called interaction foci are central to mental activity.

    Purpose of the Study:

    • To explore the principles of brain organization for mental activity.
    • To investigate the role of interaction foci in information synthesis and cognitive functions.
    • To map the topography of interaction foci during different mental acts.

    Main Methods:

    • Mapping of intracortical interactions to reveal dynamic structures.
    • Analysis of rhythmic characteristics and synchronization of neural activity.

    Related Experiment Videos

  • Correlation of interaction foci topography with specific mental functions.

    • Main Results:

    • Interaction foci act as centers for nervous connections, each with specific frequency characteristics.
    • These foci synthesize sensory, motivational, and memory information, forming the basis of mental functions.
    • The topography of interaction foci varies with mental acts, demonstrating functional specialization (e.g., perception vs. thinking).

    Conclusions:

    • Mental functions are based on informational synthesis within interaction foci, characterized by a stable core and adaptable peripheral connections.
    • The unique configuration of peripheral connections contributes to the distinct nature of subjective psychic experiences.
    • Consciousness may involve spatially separated functions, including self-integration and communication.
