Ventromedial prefrontal cortex mediates visual attention during facial emotion recognition

Area of Science:

• Neuroscience
• Cognitive Psychology
• Social Neuroscience

Background:

• The ventromedial prefrontal cortex (vmPFC) is recognized for its role in social and emotional regulation.
• Previous research primarily linked vmPFC to higher-order decision-making and valuation.
• The precise mechanisms underlying vmPFC's broad regulatory functions are not fully understood.

Purpose of the Study:

• To investigate if the vmPFC is essential for basic attentional orienting to social and emotional stimuli.
• To explore the vmPFC's role beyond deliberative processes in social cognition.

Main Methods:

• Utilized eye-tracking technology during a facial emotion recognition task.
• Examined a sample of patients with lesions in the ventromedial prefrontal cortex.
• Assessed visual attention patterns towards different facial regions and emotions.

Main Results:

• Bilateral vmPFC damage significantly impaired visual attention to the eye regions of faces.
• This attentional deficit was particularly pronounced when viewing fearful faces.
• The findings highlight a novel role for the vmPFC in controlling eye movements towards emotional facial expressions.

Conclusions:

• The ventromedial prefrontal cortex plays a crucial role in basic attentional control, specifically directing gaze towards emotionally salient facial cues.
• This study uncovers a previously unrecognized function of the vmPFC in fundamental social-emotional processing.
• vmPFC damage disrupts the ability to orient attention to socially meaningful stimuli, impacting emotion recognition.
