| Research Abstract |
We approached some anomalies of economics by using the knowledge and techniques of neuroscience. In the experiments, we found some significant correlations between the decision making under uncertainty and indexes of physiological chemical substances (e.g., Testosterone). The subjects also underwent functional magnetic resonance imaging (3T-fMRI) to observe the activation of their amygdala, both under risk (i.e., with known probability) and under ambiguity (i.e., with unknown probability) while viewing blocks of unpleasant images and neutral images. The results suggest that the activity of inhibitory system under ambiguity may be different from that in risky situation.
