Dora Duka: human psychopharmacology, alcohol, memory, impulsivity, associative learning, attentional bias, drug addiction

How does drug and alcohol abuse (including binge drinking and multiple withdrawals) alter brain structure and function, and what are the cognitive and emotional consequences that contribute to the maintenance of addiction?

How do variations in levels or patterns of expression of GABRA2 gene in humans predispose to stress responsiveness, and influence the ability of stressful events to mediate addictive behaviours?

How do drug associated stimuli capture attention and control drug seeking behaviour? What are the cognitive and brain mechanisms underlying these effect?

What are the mechanisms mediating the effects of stress on craving for and consumption of alcohol in binge drinkers? reduced inhibitory control or increased responsiveness of reward pathways?

What are the mechanisms by which impulsivity contribute to addictive behaviours?

Dai Stephens: behavioural neuroscience, behavioural genetics, alcohol, cocaine, addiction, impulsivity, GABAA receptors, incentive Learning, psychopharmacology

How does drug and alcohol abuse alter the brain, and what are the consequences for future control over drug taking?

How do differences in function of GABAergic synapses in the nucleus accumbens alter the rewarding effects of drugs of abuse? And how do genetic variations in these systems interact with environmental events to influence drug taking and seeking?        

How do genes interact with early-life stress to influence risk for addictive behaviour?

How can we make sure that what we study in animals has relevance for human addictive behaviour?

Research Students:

Hans Crombag: incentive learning, addiction, appetite

How does associative learning modulate motivated action and decision-making?

What physiological- and neuronal substrates mediate incentive learning?

How do (drug) experience-dependent changes in corticostriatal circuitries affect purposive action and decision-making, including overeating and addiction?

How can basic psychology- and neuroscience research translate to inform our debate and understanding of compulsions (addiction), free-will or self-control?

Sarah King: molecular and neurobiological mechanisms; gene manipulation and molecular biology

How do specific genetic polymorphisms affect cognition/addictive behaviours across the lifespan, and how do drugs interact with these processes?

How do subtypes of GABAA receptor in specific cells of the nucleus accumbens mediate the rewarding effects of drugs of abuse?

How do variations in GABAA receptor subunit genes interact with environmental events (e.g. early life stress) to influence addiction-related behaviour?

How does drug exposure (nicotine) in early development impact on corticothalamic circuits and drive changes in stress reactivity / behaviour in adulthood?

What are the molecular consequences of adolescent binge alcohol exposure that underlie changes in behaviour?

Tamzin Ripley: consequences of addiction: impact of drugs or early life stress on adult behaviour

What are the long-term consequences of binge exposure to alcohol during adolescence on impulse control and cognition?

How do early life stressful experiences alter emotional and cognitive processes, and how might these changes effect susceptibility to future drug taking?

What are the brain mechanisms that support cognitive flexibility? And how can such knowledge improve the treatment of schizophrenia?

Mike Morgan: experimental neuropsychopharmacology of addiction; psychopharmacology of novel abused substances

How does drug and alcohol abuse alter the brain, and what are the consequences for future control over drug taking?

What are the neuropsychological impairments and deficits in social cognition associated with illicit drug use?

Do subtypes of impulsivity provide candidate endophenotypes for addiction?

Eisuke Koya: neuronal ensembles, associative learning, obesity, addiction, synaptic physiology, immunohistochemistry

Are learned associations about food and drug rewards and their administration environment mediated by neuronal ensembles in motivationally relevant areas such as the medial prefrontal cortex and nucleus accumbens?

Do the neurons that mediate these learned associations exhibit unique synaptic physiology? Thus, are these neurons part of a unique neuronal circuit?
