Recent Research:
In a recent study, Professor Gibson Brandon and her coauthors contribute to the neuro-finance literature by focusing on how individuals differ when they decide to tell the truth or to be dishonest in situations where truthfulness comes at a monetary cost. The data, obtained using functional magnetic resonance imaging and measured brain activity and connectivity, reveals that individuals with stronger honesty-related values exhibit prefrontal interactions when the costs of honesty are high. Furthermore, the authors’ dynamic causal modelling results specified the direction of these interactions by showing that the coupling in participants with strong honesty-related values was best explained by a model in which the dorsolateral prefrontal cortex receives input from the inferior frontal gyrus, and the dorsomedial prefrontal cortex and inferior frontal gyrus are bidirectionally coupled. Together, these findings provide novel insights into how prefrontal connectivity underpins individual variability in honesty-related values.
