Acute right hemisphere lesions, particularly in the insula and frontal operculum, impair emotional and empathetic responses to financial gains and losses. Damage affects both self-experienced and observed financial outcomes.

Area of Science:

  • Neuroscience
  • Psychology
  • Neurology

Background:

  • The right hemisphere plays a crucial role in emotional processing and empathy.
  • Understanding how focal brain lesions impact financial decision-making and emotional responses is vital.

Purpose of the Study:

  • To investigate the specific components of valuation and emotional responses affected by acute right hemisphere lesions.
  • To examine the impact of these lesions on emotional empathy when observing a partner's financial outcomes.

Main Methods:

  • Assessed skin conductance response (SCR) and self-reported emotional ratings in patients with acute right hemisphere strokes and healthy controls.
  • Participants experienced winning and losing money in a roulette task, and observed a partner experiencing the same.
  • Quantified the extent of brain damage, specifically focusing on the right anterior insula and frontal operculum.

Main Results:

  • Percentage of damage to the right anterior insula and frontal operculum correlated negatively with skin conductance response (SCR) to both winning and losing money.
  • Lesion extent also correlated with a reduced difference in emotional ratings between winning and losing scenarios.
  • These findings suggest these brain regions are critical for processing emotional responses to financial outcomes.

Conclusions:

  • Distinct acute right hemisphere lesions disrupt specific aspects of financial valuation and emotional regulation.
  • The right anterior insula and frontal operculum are critical for modulating physiological and subjective emotional responses to financial gains and losses, as well as empathy.
  • These findings have implications for understanding emotional deficits following stroke and their impact on financial behavior.
