Some heightened sensitivity.

Slowing of the hippocam-pal θ rhythm correlates with anesthetic-induced amnesia. Differential effects of isoflur-ane on high-frequency and low-frequency γ oscillations in the cerebral cortex and hippocampus in freely moving rats. A. High-frequency gamma oscillations and human brain mapping with electrocortico-graphy. Homeostatic control of slow-wave and spindle frequency activity during human sleep: effect of differential sleep pressure and brain topography. Electroencephalographic bicoherence is sensitive to noxious stimuli during isoflurane or sevoflurane anesthesia. Supervising anesthesiologists cannot be effectively compared according to their patients' postanesthesia care unit admission pain scores. et al. Dopamine-dependent changes in the functional connectivity between basal ganglia and cerebral cortex in humans. Contribution of parvalbumin and somato-statin-expressing GABAergic neurons to slow oscillations and the balance in beta-gamma oscillations across cortical layers. With the progressive ageing of the population, anaesthetists are increasingly faced with geriatric patients. As our patient population greys, there have been regular calls to limit anaesthetic exposure in older patients out of fear of overdose. The current concern regarding postoperative cognitive dysfunction weighs heavily on some patients' minds, while anaesthetists ponder the significance of the 'triple low' as a predictor of morbidity and mortality. 1 2 Anecdotally, elderly patients take a variable, but prolonged, amount of time to recover from anaesthesia relative to younger patients.
