DESCRIPTION:The development of a skill or habit leads to the automation of
  behaviour triggered by associated stimuli. During early learning actions 
 are goal-directed\, however with experience they can become habitual. A sh
 ift in activity from the medial to the lateral dorsal striatum is thought 
 to occur as behaviours become more habitual or skilled. I will present the
  results from a new study investigating the development of heterogeneous s
 equencing behaviour in rats with lesions to either the medial (DMS) or lat
 eral (DLS) dorsal striatum. The acquisition of sequencing behaviour was im
 paired in rats with DLS lesions yet enhanced in rats with DMS lesions. Thi
 s finding suggests the two regions may be acting competitively in the deve
 lopment of habit-like behaviour. In addition\, the DLS lesioned rats show 
 differences in action initiation and speed of sequencing without general m
 otor deficits. These results shed light on the role of the dorsal striatum
  in sequence learning and the relationship between medial and lateral stri
 atum in controlling behaviour.
