Research summary

My research is in Hedonic Neuroscience and Self-Control. What are the neural correlates of pleasures, desires, fears and aversions? How do we control our appetites and fears? How do we control our selfish interests and act prosocially?

In particular, I’m interested in the psychology, neurobiology and genetics of individual differences in complex traits linked to personality and self-control. How and why do individuals vary in their temperamental emotional reactivity and self-control and how does this influence risk for mood, obesity and addictive disorders?

Other research helps to understand how social values get translated into action. This research is being undertaken in collaboration with colleagues in the Values in Action (ViA) Centre, at Cardiff University.

Teaching summary

I currently teach on PS2019 (Research design, statistics and computing) and PS3416 (Emotion: Social and neuroscience perspectives). In addition, I supervise final year projects and medical student projects related to my research interests.

The Neuroscience of Natural Rewards: Relevance to Addictive Drugs

Key recent research findings include:

(1) Evidence for distinct neural coding of pleasant and disgusting foods in  insular cortex and pallidum of humans:

(from Beaver et al. EJN, 2007). Ongoing work is examining the neural correlates of desire and disgust for food, and how these relate to traits like   impulsivity, eating disorders and obesity. In addition, we are examining the extent to which systems that evolved to mediate the disgust response to foods   have been co-opted to mediate more complex forms of socio-moral disgust, and how food reward systems link with other positive emotions.

(2) How do drugs of abuse hijack brain 'reward’ systems? The controversial incentive-sensitization theory argues that drugs of abuse  sensitize brain mesolimbic systems of incentive salience ('wanting’), leading to compulsive intake. By studying a rare group of individuals with Parkinson’s disease who develop compulsive drug use (and other impulse control problems), we provided the first evidence that addiction could result from such an incentive sensitization mechanism:

(from Evans et al. Ann Neurol, 2006). We are currently examining the extent to which such mechanisms can be applied to other addictive and impulse-control disorders (eg. gambling and binge eating induced by dopaminergic drugs).

(3) The neurobiology of negative urgency. Urgency (the tendency to distressed-based impulsivity) is a key risk trait for addiction and impulse control. We have recently demonstrated (Boy et al. Biol Psychiatry) that individual differences in urgency are Predicted by levels of the inhibitory neurotransmitter GABA in the DLPFC. This provides novel insights into the role of GABA in various psychiatric disorders, including alcohol addiction. (new figure  to insert).

Prosocial Neuroscience
We  are interested in the neural mechanisms underpinning individual differences in empathic concern and empathic accuracy, and how these link to prosociality and  caring.

For  example, we have shown that so-called 'mirror neuron’ systems at best play a limited role in empathy – probably limited to action-oriented aspects of emotion  understanding (see e.g. Tavares et al., 2010 and von dem Hagen et al., 2009). Ongoing  work is establishing distinct neural systems for empathic concern (ventral PFC)  vs. empathic accuracy (insula).

Postgraduate research interests

I’m particularly interested at the moment in supervising projects on (1) the neuroscience  of 'wanting’ and 'liking’, and its link to addiction and obesity; (2) emotion-based dispositions to rash action (Urgency); (3) disgust; and (4) The neurobiology of social reward and punishment and links to prosocial behaviour and empathy.
