This study introduces a biologically plausible neural network for goal-directed behavior and cognitive mapping. Simulations demonstrate its ability to model animal learning and solve complex problems like the Tower of Hanoi.

Area of Science:

  • Computational Neuroscience
  • Cognitive Science
  • Artificial Intelligence

Background:

  • Understanding purposive behavior and cognitive mapping is crucial for artificial intelligence and neuroscience.
  • Existing models often lack biological plausibility or real-time processing capabilities.

Purpose of the Study:

  • To present a novel, biologically plausible neural network model for real-time purposive behavior and cognitive mapping.
  • To develop a system capable of both goal-seeking and constructing a topological cognitive map.
  • To introduce and evaluate fast-time and real-time prediction mechanisms within the network.

Main Methods:

  • Development of a neural network with integrated action (goal-seeking, motivational) and cognitive (topological map) systems.
  • Implementation of recurrent and non-recurrent network properties for map reading without modification.

  • Introduction of fast-time predictions (remote future) and real-time predictions (simultaneous with events).

    • Main Results:

    • The neural network successfully simulated latent learning and detour behavior in rats.
    • Computer simulations validated the network's capacity for real-time cognitive map updates and predictions.
    • The model demonstrated applicability to problem-solving tasks, exemplified by the Tower of Hanoi puzzle.

    Conclusions:

    • The proposed neural network offers a biologically plausible framework for understanding goal-directed behavior and cognitive mapping.
    • The model's ability to perform real-time predictions and adapt to environmental changes is a key advancement.
    • This approach holds potential for developing more sophisticated AI systems and advancing cognitive neuroscience research.
