The accurate identification of obscured and concealed objects in complex environments was an important skill required for survival during human evolution, and is required today for many forms of expertise. Here we used transcranial direct current stimulation (tDCS) guided using neuroimaging to increase learning rate in a novel, minimally guided(More)
Transcranial direct current stimulation (TDCS) is a non-invasive form of brain stimulation applied via a weak electrical current passed between electrodes on the scalp. In recent studies, TDCS has been shown to improve learning when applied to the prefrontal cortex (e.g., Kincses et al. in Neuropsychologia 42:113-117, 2003; Clark et al. Neuroimage in 2010).(More)
We have previously found that transcranial direct current stimulation (tDCS) over right inferior frontal cortex (RIFC) enhances performance during learning of a difficult visual target detection task (Clark et al., 2012). In order to examine the cognitive mechanisms of tDCS that lead to enhanced performance, here we analyzed its differential effects on(More)
UNLABELLED Monitoring and maintaining body temperature during the perioperative period has a significant impact on the risk of myocardial ischemia, cardiac morbidity, wound infection, surgical bleeding, and patient discomfort. To test the hypothesis that body temperature is inadequately monitored during regional anesthesia (RA), we randomly surveyed 60(More)
Children exposed to substantial amounts of alcohol in utero display a broad range of morphological and behavioral outcomes, which are collectively referred to as fetal alcohol spectrum disorders (FASDs). Common to all children on the spectrum are cognitive and behavioral problems that reflect central nervous system dysfunction. Little is known, however,(More)
OBJECTIVE To validate the efficacy of a radiodermatitis management protocol (which involves preventive measures, the application of preventive creams and the use of a non-adhesive, foam dressing with a silicone contact layer) at a radiation oncology department in southern Spain. METHOD An observational study was carried out on consecutive patients(More)
Dependent on maternal (e.g. genetic, age) and exposure (frequency, quantity, and timing) variables, the effects of prenatal alcohol exposure on the developing fetus are known to vary widely, producing a broad range of morphological anomalies and neurocognitive deficits in offspring, referred to as fetal alcohol spectrum disorders (FASD). Maternal drinking(More)
We report a case of postoperative bile leak originating from subvesical bile ducts. This anatomic variant of the bile duct is widely prevalent, often undiagnosed, and usually uncovered in the setting of iatrogenic biliary injury. Injury to these ducts during gallbladder surgery can be potentially averted by minimizing dissection into the hepatic parenchyma.(More)
