OBJECTIVES: This study aimed to examine one of biological correlates, pro-inflammatory cytokine, in rejection of unfair financial offers in the Ultimatum Game (UG), where the division of a sum of money is proposed and the player can accept or reject this offer.
METHODS: Nineteen participants played 20 trials of the UG as responders, and they were proposed unfair offers in a half of the trials. Baseline levels of several pro-inflammatory and anti-inflammatory cytokines, subjective happiness, and depression of them were measured.
RESULTS: Participants with higher levels of the pro-inflammatory cytokine, interleukin (IL)-6 rejected fewer unfair offers. This effect of IL-6 levels on decision-making was independent from other pro-inflammatory cytokines, anti-inflammatory cytokines, subjective happiness, and depression.
CONCLUSIONS: These results suggested that chronic higher levels of IL-6 might affect functions of neural regions related to decision making, and thus can modulate rejection of unfair offers.

Background: Individuals with psychopathy have an increased tendency toward certain types of aggression. We hypothesized that successful psychopaths, who have no criminal convictions but can be diagnosed with psychopathy in terms of personality characteristics, are skilled at regulating aggressive impulses, compared to incarcerated unsuccessful psychopaths. Methods: In this block-designed functional magnetic resonance imaging (fMRI) study, we sought to clarify the neural mechanisms underlying differences in frustration-induced aggression as a function of psychopathy in non-criminal populations. Twenty male undergraduate students who completed a self-report psychopathy questionnaire were scanned while they completed a task in which they either could or could not punish other individuals who made unfair offers of monetary distribution. Results: Individuals with high psychopathic tendencies were less likely to make a decision to inflict costly punishment on people proposing unfair offers. During this decision-making, psychopathy was associated with less amygdala activity in response to the unfairness of offers. Moreover, the amygdala dysfunction in psychopathic individuals was associated with reduced functional connectivity with dopaminergic-related areas, including the striatum, when punishment was available compared to when it was unavailable. Limitations: The possibility that levels of psychopathic traits in a regular population were milder than in incarcerated populations cannot be ruled out. Conclusions: The findings indicate that amygdala dysfunction underlies affective deficits of psychopathy. We propose that the insensitivity of the amygdala to the affective significance of social stimuli contributes to an increased risk of violation of social norms, but enhances the ability to attenuate impulses toward maladaptive aggression in successful psychopaths. © 2012 Elsevier B.V.

Mindfulness is currently attracting a great deal of attention as a psychotherapy technique. It is defined as bringing one's complete attention to the experiences occurring in the present moment in a nonjudgmental or accepting way. The Five Facet Mindfulness Questionnaire (FFMQ) was developed to assess individual differences in mindfulness states. The FFMQ is composed of five facets representing elements of mindfulness: non-reactivity to inner experience, non-judging, acting with awareness, describing, and observing. In the present study, we applied voxel-based morphometry to investigate the relationship between the brain structure and each facet as measured by the FFMQ. The results showed a positive association between the describing facet of mindfulness on the FFMQ and gray matter volume in the right anterior insula and the right amygdala. In conclusion, mindfulness was related with development in parts of the somatic marker circuit of the brain. © 2012 Murakami et al.
