Conditioned responding to drug-predictive discrete cues can be strongly modulated by drug-associated contexts. We tested the hypothesis that differential recruitment of the nucleus accumbens (NAc) core and shell mediates responding to drug cues in a drug vs non-drug context. Rats were trained to discriminate between two 10-s auditory stimuli: one stimulus(More)
The basolateral amygdala complex (BLA) has been identified as a critical structure mediating fear extinction. However, little is known about the functional role of neurons in the BLA during the extinction of a reward-seeking behavior. Here, we used in vivo electrophysiology procedures in freely moving rats to investigate whether and how the BLA encodes the(More)
OBJECT Proximal junctional kyphosis (PJK) is a common and significant complication after corrective spinal deformity surgery. The object of this study was to compare-based on clinical outcomes, postoperative proximal junctional kyphosis rates, and prevalence of revision surgery-proximal thoracic (PT) and distal thoracic (DT) upper instrumented vertebra(More)
OBJECT Administrative databases are increasingly being used to establish benchmarks for quality of care and to compare performance across peer hospitals. As proposals for accountable care organizations are being developed, readmission rates will be increasingly scrutinized. The purpose of the present study was to assess whether the all-cause readmissions(More)
OBJECT Despite increasing numbers of patients with adult spinal deformity, it is unclear how to select the optimal upper instrumented vertebra (UIV) in long fusion surgery for these patients. The purpose of this study was to compare the use of vertebrae in the upper thoracic (UT) versus lower thoracic (LT) spine as the upper instrumented vertebra in long(More)
