Following the loss of a sensory modality, such as deafness or blindness, crossmodal plasticity is commonly identified in regions of the cerebrum that normally process the deprived modality. It has been hypothesized that significant changes in the patterns of cortical afferent and efferent projections may underlie these functional crossmodal changes. However, studies of thalamocortical and corticocortical connections have refuted this hypothesis, instead revealing a profound resilience of cortical afferent projections following deafness and blindness. This report is the first study of cortical outputs following sensory deprivation, characterizing cortical projections to the superior colliculus in mature cats (

Until recently, there were few rodent models available to study the interaction of post-traumatic stress disorder (PTSD) and drug taking. Like PTSD, single prolonged stress (SPS) produces hypothalamic-pituitary-adrenal (HPA) axis dysfunction and alters psychostimulant self-administration. Other stressors, such as isolation stress, also alter psychostimulant self-administration. However, it is currently unknown if isolation housing combined with SPS can alter the acquisition or maintenance of cocaine self-administration. The current study applied modified SPS (modSPS; two hours restraint immediately followed by cold swim stress) to rats raised in an isolation condition (Iso), enrichment condition (Enr), or standard condition (Std) to measure changes in …
What Are The Characteristics Of Vitamin D Metabolism In Opioid Dependence? An Exploratory Longitudinal Study In Australian Primary Care, Albert Stuart Reece, Gary Hulse
What Are The Characteristics Of Vitamin D Metabolism In Opioid Dependence? An Exploratory Longitudinal Study In Australian Primary Care, Albert Stuart Reece, Gary Hulse
Research outputs 2014 to 2021
OBJECTIVE: Compare vitamin D levels in opioid dependence and control population and adjust for relevant confounding effects. Nuclear hormone receptors (including the vitamin D receptor) have been shown to be key transducers and regulators of intracellular metabolism and comprise an important site of pathophysiological immune and metabolic dysregulation potentially contributing towards pro-ageing changes observed in opioid-dependent patients (ODPs).
DESIGN: Longitudinal prospective comparing ODPs with general medical controls (GMCs).
SETTING: Primary care.
PARTICIPANTS: Prospective review comparing 1168 ODP (72.5% men) and 415 GMC (51.6% men, p
INTERVENTIONS: Nil. Observational study only.
PRIMARY AND SECONDARY OUTCOMES: Serum vitamin D levels and relevant …
