The re-establishment of conscious awareness after discontinuing general anesthesia has often been assumed to be the inverse of loss of consciousness. This is despite the obvious asymmetry in the initiation and termination of natural sleep. In order to characterize the restoration of consciousness after surgery, we recorded frontal electroencephalograph(More)
The brain is a large network of interconnected neurons where each cell functions as a nonlinear processing element. Unraveling the mysteries of information processing in the complex networks of the brain requires versatile neurostimulation and imaging techniques. Optogenetics is a new stimulation method which allows the activity of neurons to be modulated(More)
The practice of neuroanesthesia is unique in that the target organ of both the surgeon and the anesthetist is one and the same. Thus, the surgical goals have a profound impact on the constraints that the anesthesiologist must work within. In order to appropriately anesthetize the patient for neurosurgery, an understanding of the interrelationships of(More)
BACKGROUND Obstructive sleep apnoea (OSA) is one of the most common public health problems in adults. Patients with OSA are prone for excessive adipose tissue deposition in the neck, which in turn, increases the upper airway narrowing. Of the imaging modalities available for assessing the upper airway, magnetic resonance imaging (MRI) is found to be useful(More)
