Brain Activity Follow Up of Stock Market Financial Variables

Efficiency Market hypothesis assume that all investors reason in the same way to make their financial decisions. In contrast, Neurosciences have provided strong evidences that cognitive diversity is the hallmark of human intelligence. Neurofinances has shown that volunteers learned different profitable financial decision-making strategies depending on the kind of market they begun to trade. Here, we decide to further explore this hypothesis by studying a possible correlation between brain activity and the financial variables in a stock market game and to test if this correlation differ between experimental groups that trade in different market conditions. Present results show that volunteers had different perceptions of the studied financial variables depending if they initially traded in a bear or a bull market. Our findings are consistent with the hypothesis that different neural circuits were learned to monitor the different financial variables studied here, depending on market conditions.
