Neural representation of maternal face processing: a functional magnetic resonance imaging study

Area of Science:

• Neuroscience
• Developmental Psychology
• Social Cognition

Background:

• The mother-child relationship is critical for emotional development and adult psychopathology.
• Understanding neural responses to maternal figures is key to comprehending attachment and its long-term effects.

Purpose of the Study:

• To investigate brain activity in healthy adult women when processing images of their own mother.
• To explore how different brain regions respond to maternal faces during various cognitive tasks.

Main Methods:

• Functional magnetic resonance imaging (fMRI) was employed in ten healthy adult women.
• Participants viewed images of their mother, a friend, and strangers, performing passive viewing, valence, and salience evaluations.

Main Results:

• Significant activation was observed in the posterior cingulate cortex-precuneus (PCC-Pcu), ventromedial prefrontal cortex-anterior cingulate cortex (VMPFC-ACC), and dorsolateral prefrontal cortex (DLPFC) when viewing mothers' faces.
• The VMPFC-ACC uniquely distinguished processing of the mother's face from a close friend's face.
• PCC-Pcu activation showed a graded response (mother > friend > strangers) and varied with mothering style.

Conclusions:

• Brain regions involved in emotional and self-relevant processing are activated by maternal face perception.
• Findings support a neural basis for maternal attachment.
• This research provides a foundation for studying the effects of disrupted maternal attachment on emotional development.
