Neuroeconomics integrates neuroscience and economics to understand financial decision-making. This review explores brain mechanisms, structures, and diseases impacting economic choices, highlighting the role of reward and aversion systems.
Area of Science:
- Neuroeconomics as an emerging interdisciplinary field.
- Leveraging neuroimaging techniques like functional magnetic resonance imaging (fMRI).
Background:
- Financial decision-making is influenced by complex brain processes.
- Advances in neuroimaging have significantly propelled neuroeconomics research.
Purpose of the Study:
- To review neurological mechanisms underlying financial decisions.
- Identify key brain structures involved in economic choices.
- Examine diseases affecting financial behavior.
Main Methods:
- Non-systematic literature review.
- Searched PubMed, Tripdatabase, and Cochrane Library.
- Included bibliographies from the Spanish Neuroeconomics Association.
Main Results:
- Reward and loss aversion systems balance economic decisions.
- Dopamine and specific brain structures (amygdala, insula, medial prefrontal cortex, cingulate cortex, accumbens, ventral tegmental area) are crucial.
- Imbalances linked to depression, mania, alcoholism, gambling, and impulse control disorders.
Conclusions:
- Neurologists have a key role in neuroeconomics.
- The specialty is well-positioned to study brain functions in economic contexts.
- Neuroeconomics is a field with significant future growth potential.
