Area of Science:

  • Cognitive Neuroscience
  • Neuroscience
  • Visual Perception

Background:

  • Eye movements trigger rapid changes in brain functional connectivity.
  • Understanding task-dependency in these reconfigurations is crucial for cognitive science.

Purpose of the Study:

  • To investigate how memory encoding and retrieval tasks influence brain functional connectivity during visual exploration.
  • To determine if task demands differentially shape network configurations in early visual processing.

Main Methods:

  • Utilized multichannel electroencephalography (EEG) to record brain activity.
  • Estimated functional connectivity using weighted phase lag index (wPLI) in theta, alpha, and beta bands.
  • Analyzed global and local graph measures of connectivity networks time-locked to fixation onsets.

Main Results:

  • Significant differences in network measures (e.g., mean path length, diameter) were observed between encoding and retrieval tasks, primarily in the alpha band.
  • Memory encoding demonstrated a more segregated network configuration compared to memory retrieval.
  • These task-related differences emerged immediately after fixation onset and persisted throughout the early visual processing period (lambda complex).

Conclusions:

  • Memory encoding and retrieval tasks differentially modulate functional connectivity networks during early visual perception.
  • Task requirements dynamically control brain network configurations, influencing visual input processing at each fixation.
  • Findings highlight the adaptive nature of neural networks in response to cognitive demands during visual exploration.
