fNIRS + Eyetracking

fNIRS + Eyetracking – Neural Correlates of Visual Attention

Simultaneous Measurement of Brain Activity and Gaze Behavior

The integration of functional Near-Infrared Spectroscopy (fNIRS) with eyetracking technology allows researchers to connect brain hemodynamic responses with real-time visual attention and gaze patterns. While eyetracking captures where a subject is looking, how their gaze shifts, and pupil dilation, fNIRS records the corresponding brain activity by measuring changes in oxy- and deoxyhemoglobin concentrations.

This powerful combination facilitates a deeper understanding of visual cognition, attention dynamics, and decision-making processes—particularly in naturalistic, dynamic, or interactive settings that extend beyond traditional lab environments.

Key Features
  • Visual Cognition Insights: Links brain activation to eye movement and gaze behavior.
  • Naturalistic Studies: Enables research in real-world or ecologically valid visual scenarios.
  • Attention Monitoring: Tracks visual focus and mental effort through gaze and pupil data.
  • Enhanced Behavioral Correlation: Provides a rich behavioral layer to interpret neural signals more accurately.

This integration is ideal for studies in psychology, neuroergonomics, education research, and human-computer interaction—where understanding the interplay between attention and brain activity is critical.
