The ability to distinguish currently relevant from familiar but irrelevant memories is important in everyday life. We used functional magnetic resonance imaging to examine the neural correlates of age differences in the ability to withstand interference from similar past events. Younger and older adults worked on a continuous recognition task consisting of 3 consecutive runs. Each run was compo...

EEG was monitored at bilateral scalp sites outside the operative field during hypotensive aneurysm surgery in 21 patients. Mean arterial blood pressure at axillary level was 50-60 mm Hg (average 55 mm) for 1.9-5.3 hours (average 3.6). Four new deficits were noted immediately post-operatively, all related to the operated site: these were attributable to intra-operative rupture with forced vascul...

BACKGROUND The majority of spinal surgeons now utilize intraoperative neurophysiological monitoring (IONM) during spinal procedures to limit the risk of inadvertent injury. Nevertheless, probably the most frequent error is the failure of the surgeon and IONM to obtain adequate preoperative baselines (e.g. before intubation or positioning). METHODS Intraoperative neural monitoring should begin...

The role of the orbitofrontal cortex in social behavior remains a puzzle. Various theories of the social functions of the orbitofrontal cortex focus on the role of this area in either emotional processing or its involvement in online monitoring of behavior (i.e., self-monitoring). The present research attempts to integrate these two theories by examining whether improving the self-monitoring of...

Selective Dorsal Rhizotomy (SDR) is a neurosurgical procedure currently used as a surgical treatment of children with spasticity in their legs. In SDR, the dorsal roots from L2 to S1 or S2 is partially sectioned. The primary goal of SDR is to reduce spasticity and improve the range of movement with preservation of muscle strength. The dorsal roots involved in spasticity are identified on the ba...

background and objective: obstructive sleep apnea (osa) is a disease with serious consequences. many portable devices have been developed to overwhelm some of limitations in the accessibility of the gold standard test for osa, polysomnography (psg). this study aimed to determine diagnostic accuracy of a portable sleep apnea screener against psg in patients of a sleep clinic. materials and metho...
