The aim of the present study was to explore brain activities associated with creativity and expertise in literary writing. Using functional magnetic resonance imaging (fMRI), we applied a real-life neuroscientific setting that consisted of different writing phases (brainstorming and creative writing; reading and copying as control conditions) to(More)
In this study we investigated the responsiveness of near-infrared spectroscopy (NIRS) recordings measuring regional cerebral tissue oxygenation (rSO2) during hypoxia in apneic divers. The goal was to mimic dynamic hypoxia as present during cardiopulmonary resuscitation, laryngospasm, airway obstruction, or the "cannot ventilate cannot intubate" situation.(More)
BACKGROUND Transfusion of allogeneic blood influences outcome after surgery. Despite widespread availability of transfusion guidelines, transfusion practices might vary among physicians, departments, hospitals and countries. Our aim was to determine the amount of packed red blood cells (pRBC) and blood products transfused intraoperatively, and to describe(More)
Plantar paw skin temperature development was examined in 26 healthy male albino rats using Heimann's infrared thermometer KT 41. This examination was carried out on two groups of 12 and 14 male rats after intraplantar injection of kaolin, carrageenin, and dextran. Normal untreated animals showed a distinct circadian course of daily temperature, with minimal(More)
Prolonged breath-hold causes complex compensatory mechanisms such as increase in blood pressure, redistribution of blood flow, and bradycardia. We tested whether apnea induces an elevation of catecholamine-concentrations in well-trained apneic divers.11 apneic divers performed maximal dry apnea in a horizontal position. Parameters measured during apnea(More)
We report on the case of a 33 year old woman with acute tetraparesis and radiological evidence of atlantoaxial dislocation who had to undergo several attempts at osteosynthetic stabilisation of the cervical spine. She was afflicted with a spastic walk since the early years of childhood which had been explained by encephalitis after umbilical sepsis. The(More)
In continuation of earlier thermometric investigations on experimental inflammations in rats we studied the effect of a single local cold application on paw skin temperature after injection of caolin , carrageenan and dextran. In all cooling experiments a highly significant drop of skin temperature of the inflamed paw could be demonstrated which came up to(More)
In case of apnea, arterial partial pressure of oxygen (pO2) decreases, while partial pressure of carbon dioxide (pCO2) increases. To avoid damage to hypoxia sensitive organs such as the brain, compensatory circulatory mechanisms help to maintain an adequate oxygen supply. This is mainly achieved by increased cerebral blood flow. Intermittent hypoxia is a(More)
