Biochemical Basis of Dopamine and Its Role in Neurofinancial Decision Making

Abstract

Neurofinance or neuroeconomics is generally examined under three main categories. The first comprises studies focusing on specific brain regions—particularly the interactions between the frontal cortex and the limbic system—and investigates which areas show activation under various decision-making conditions. The second category encompasses research conducted through the lens of psychopathology. The third centers on the brain’s biochemical processes, especially those involving neurotransmitters and the endocrine system. This study aims to provide a descriptive overview of dopamine, one of the most extensively studied neurochemicals in this field, and to interpret the findings within the conceptual framework of neurofinance. In doing so, the study seeks to demonstrate that what is commonly known in everyday language as the 'pleasure chemical' is, in fact, far more complex and functionally diverse than mere hedonic processing. By compiling current scientific findings within the scope of available research, the paper aspires to contribute to a deeper understanding of the dopaminergic system and its role in financial decision-making processes.
