EEG coherence analysis reveals distinct brain activity patterns during the Stroop task. Higher cortical coherence in specific frequency bands differentiates congruent from incongruent conditions, correlating with reaction times.

Area of Science:

  • Cognitive Neuroscience
  • Neurophysiology

Background:

  • The Stroop task is a classic test of executive function, measuring selective attention and cognitive control.
  • Electroencephalography (EEG) and event-related potentials (ERPs) are common methods for studying brain activity during cognitive tasks.

Purpose of the Study:

  • To analyze the Stroop effect using EEG coherence analysis alongside traditional behavioral and ERP measures.
  • To investigate the dynamic evolution of functional cortical relationships during the Stroop task.

Main Methods:

  • Applied a dynamic approach for continuous coherence estimation in EEG data.
  • Analyzed behavioral data (reaction time) and ERPs from 10 normal subjects.
  • Focused on the 13-20 Hz frequency band for coherence analysis.

Main Results:

  • Instantaneous coherence analysis in the 13-20 Hz band differentiated congruent and incongruent Stroop conditions.
  • Higher coherence values were observed in left frontal and parietal areas for incongruent conditions.
  • Peak synchrony (maximal coherence time-points) correlated with reaction times, particularly in the incongruent case.

Conclusions:

  • EEG coherence analysis provides insights into the neural dynamics underlying cognitive control during the Stroop task.
  • Functional cortical interactions, especially in frontal and parietal regions, are modulated by task difficulty.
  • Dynamic coherence measures offer a procedural distinction between task conditions and relate to behavioral performance.
