Area of Science:

  • Neuroscience and Cognitive Science
  • Computational Neuroscience
  • Brain-Computer Interfaces

Background:

  • Working-memory tasks are known to increase rhythmic brain activity, suggesting neural information exchange.
  • Electroencephalography (EEG) measures brain waves, offering a potential method for extracting this encoded information.
  • Artificial neural networks (ANNs) can model complex systems, including stimulus-response dynamics with state observation.

Purpose of the Study:

  • To investigate the feasibility of extracting information from brain waves during cognitive tasks.
  • To apply an artificial neural network (ANN) as a stimulus-response model with a state observer to EEG data.
  • To determine if neural signals can predict task responses.

Main Methods:

  • Recorded EEG signals from three subjects performing a modified Sternberg working-memory task.

  • Utilized an ANN to analyze phase-demodulated theta-band EEG signals.
  • Focused analysis on EEG data recorded 1 second prior to the subject's response.

    • Main Results:

    • Successfully identified a stimulus-response model by observing theta-band EEG signals.
    • Achieved an average prediction accuracy of 75% for subject answers across all participants.
    • Demonstrated that EEG signals contain predictable information about cognitive task outcomes.

    Conclusions:

    • It is possible to observe system states through EEG signal analysis.
    • Predicting correct answers from cognitive tasks using EEG signals is feasible.
    • ANNs provide a viable method for decoding neural information exchange during working memory.
