This study reveals that experiencing anger in healthy men is linked to increased brain activity in specific regions, including the orbitofrontal cortex and anterior cingulate cortex. These findings offer insights into the neurobiology of anger.

Area of Science:

  • Neuroscience
  • Psychology
  • Neuroimaging

Background:

  • Understanding the neurobiological basis of emotional processing is crucial for psychiatric illness research.
  • Investigating normal emotional responses provides a foundation for understanding psychopathology.

Purpose of the Study:

  • To examine the functional neuroanatomy of anger in healthy individuals.
  • To identify brain regions associated with the subjective experience of anger.

Main Methods:

  • Eight healthy men participated in the study.
  • Anger and neutral emotional states were induced using autobiographical narrative scripts.
  • Positron emission tomography (PET) measured regional cerebral blood flow (rCBF) during imagined emotional states.

Main Results:

  • Anger was associated with increased rCBF in the left orbitofrontal cortex.
  • Activation was observed in the right anterior cingulate cortex (affective division).
  • Bilateral anterior temporal poles showed increased activity during anger.

Conclusions:

  • The subjective experience of anger correlates with elevated rCBF in anterior paralimbic brain regions.
  • Findings contribute to understanding the neural correlates of emotional states.
