Highly intelligent individuals show more efficient cognitive resource distribution during oddball tasks. Their brain activity patterns, analyzed via LORETA, suggest optimized cortical gray matter engagement compared to less intelligent individuals.

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Brain Imaging

Background:

  • Cognitive efficiency varies with intelligence levels.
  • Understanding neural correlates of cognitive processing is crucial.
  • Oddball tasks are standard paradigms for studying attention and cognitive control.

Purpose of the Study:

  • To investigate differences in brain activity between high and low intelligence individuals during oddball tasks.
  • To analyze current density and cortical gray matter volume using LORETA.
  • To explore the neural basis of efficient cognitive resource allocation.

Main Methods:

  • Low Resolution Brain Electromagnetic Tomography (LORETA) was used for analysis.
  • Participants included individuals with high (IQ=127) and low (IQ=87) intelligence.

  • Auditory and visual oddball tasks were employed to assess cognitive responses.

    • Main Results:

    • Highly intelligent individuals exhibited decreased activated cortical gray matter volume.
    • Low intelligent individuals displayed a reversed pattern of cortical activity.
    • In auditory tasks, high intelligence was linked to increased current density and left-hemispheric source localization.

    Conclusions:

    • High intelligence correlates with more efficient distribution of cognitive resources.
    • Distinct patterns of cortical activity underlie cognitive processing differences.
    • Brain electromagnetic tomography provides insights into intelligence-related neural efficiency.
