Area of Science:

  • Neuroscience
  • Computational Neuroscience
  • Biomedical Engineering

Background:

  • Increasing mental stress poses risks for mental illnesses like depression and anxiety.
  • Early detection of mental stress sources is crucial for timely intervention.
  • This study addresses the need to identify the neurological origins of mental stress.

Purpose of the Study:

  • To pinpoint the exact location of brain activity sources related to mental stress.
  • To analyze mental conditions during mental arithmetic tasks across different frequency bands.
  • To map brain topography and identify areas of active potentials.

Main Methods:

  • Development and application of the Novel Cluster Ensemble Verifier (CLEVER) algorithm.
  • Integration of clustering and source localization techniques for precise origin identification.
  • Utilizing Independent Component Analysis (ICA) and topographic plots to correlate brain activity with identified clusters.

Main Results:

  • The CLEVER algorithm efficiently identifies the source location of brain activity.
  • Topographic plots from ICA correlate with generated clusters, indicating specific brain regions.
  • Significant brain source activation, particularly in occipital and parietal areas, was observed during mental arithmetic tasks.

Conclusions:

  • Mental arithmetic calculations engage both occipital and parietal brain regions.
  • Visualization of numbers during problem-solving contributes to occipital area activity.
  • The CLEVER algorithm effectively verifies the origin of brain activity in these key areas.
