How does the brain control impulsive and compulsive actions and stop inappropriate or unwanted behaviour? This question is relevant to many illnesses where brain function is altered (e.g,. ADHD, Parkinson's disease, OCD, schizophrenia, compulsive gambling, eating disorders and drug addiction), each of which has symptoms of excessive or unwanted impulsive/compulsive behaviour.
Models of rodent behaviour permit us to study the anatomy and pharmacology of inhibitory failure in great detail. We develop behavioural tests that can be used in rats and mice to analyse drug actions on behaviour and often these behavioural methods can translate directly with patient assessment in the clinic. This may improve the development of treatment strategies that would not otherwise be possible or practical from studies of patient populations alone.
