Question: Do brain neuroplastic changes accompany anxiety and memory deficits in a model of complex regional pain syndrome?
Answer: The study findings provide novel observations regarding behavioral changes and brain plasticity in a mouse model of CRPS. In addition to elucidating some of the supraspinal correlates of the syndrome, this work supports the potential use of therapeutic interventions that not only directly target sensory input and other peripheral mechanisms, but also attempt to ameliorate the broader pain experience by modifying its associated cognitive and emotional comorbidities.
yes

Question: Is aMPK-dependent inhibitory phosphorylation of ACC essential for maintaining myocardial fatty acid oxidation?
