The cerebellum is increasingly recognised as a contributor to pain, especially towards affective-motivational facets, including relief-seeking from aversive experiences. Few have specifically investigated this, and much less in females, despite the notable prevalence of chronic pain in this population.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>\n                      <jats:italic>Objectives<\/jats:italic>\n                    <\/jats:title>\n                    <jats:p>To examine preference to seek cannabidiol- or oxycodone-analgesia, and cellular changes to the cerebellum in a female adolescent rat model of neuropathic pain.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>\n                      <jats:italic>Methods<\/jats:italic>\n                    <\/jats:title>\n                    <jats:p>We used a sciatic nerve chronic constriction injury (CCI) to model neuropathic pain in 6-week-old female rats and assessed thermal\/mechanical nociception and anxiety-like behaviour. Preference for cannabidiol or oxycodone was quantified in a conditioned place preference paradigm. Immunostained and cleared cerebella were analysed for calbindin-positive Purkinje cells and parvalbumin-positive molecular layer interneurons within anterior (II\u2013III, IV\u2013V) and posterior (VI\/Simplex, VII\/Crus I) lobules.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>\n                      <jats:italic>Results<\/jats:italic>\n                    <\/jats:title>\n                    <jats:p>CCI evoked heat and cold allodynia, increased anxiety-like behaviour, and produced a place preference for cannabidiol and oxycodone.
