A specific role for posterior dorsolateral striatum in human habit learningTricomi, Balleine, & O’Doherty (2009)European journal of neuroscience Extensive training on a free-operant task reduces the sensitivity of participants’ behaviour to a reduction in outcome value. There is an increase in task-related cue sensitivity in a right posterior putamen/globus pallidus region as training progressed.Cue-driven activation in a specific region of dorsolateral posterior putamen may contribute to the habitual control of behaviour in humans. The development of habits allows responses to be efficiently executed, freeing up valuable cognitive resources.Different neural systems contribute to habitual and goal-directed behaviour and learning. Goal directed action are in the prefrontal cortex and the dorsomedial striatum. Habit-based behaviour are in the dorsolateral striatum There is a habit learning system in humans.There is a region in the posterior putamen extending into the globus pallidus that becomes increasingly sensitive to stimuli that were associated with a particular behavioural response, consistent with a potential role in S-R learning. The posterior putamen/globus pallidus region may play a central role in the development and/or control of habitual behaviour in humans.The transition from goal-directed to habitual control of behaviour is highly dynamic and the early phase of the habit learning process occurs even while behaviour is still...
