Sleep and anesthesia resemble in many ways at a first glance. The most prominent common feature of course is the loss of consciousness, i.e. the loss of awareness of external stimuli. However a closer look at the loss of consciousness reveals already a difference between sleep and anesthesia: anesthesia is induced by an anesthetic drug whereas we may fall asleep without external cause. Other questions may arise about the difference of the two effects: do we dream during surgery under anesthesia, do we feel pain during sleep? Essentially, we may ask: what is common and what are the differences between sleep and anesthesia? To answer these questions, we may take a look at the neural origin of both effects and the involved physiological pathways. In which way do they resemble? Moreover, we ask what are the detailed features of normal sleep and general anesthesia as applied during surgery and which features exist in both phenomena? If yes in which way? To receive answers to these questions, it is necessary to consider several experimental techniques that reveal underlying neural mechanisms of sleep and anesthesia. Moreover, theoretical models of neural activity may model both phenomena and comes up with predictions or even theories on the underlying mechanisms. Such models may attack several different description levels, from the microscopic level of single neurons to the macroscopic level of neural populations. Such models may give deeper insight into the phenomena if their assumptions are based on experimental findings and their predictions can be compared to experimental results. This comparison step is essential for valuable theoretical models. The book is motivated by two successful workshops on anesthesia and sleep organized during the Computational Neuroscience Conferences in Toronto in 2007 and in Berlin 2009. It aims to cover all the previous aspects with a focus on the link to experimental findings. It elucidates important issues in theoretical models that at the same time reflect some current major research interests. Moreover it considers some diverse issues which are very important to get an overview of the fields. For instance, the book discusses not only neural activity in the brain but also the effects of general anesthesia on the cardio-vascular system and the spinal cord in the context of analgesia. In addition, it considers different experimental techniques on various spatial scales, such as fMRI and EEG-experiments on the macroscopic scale and single neuron and LFP-measurements on the microscopic scale. In total all book chapters reveal aspects of the neural correlates of sleep and anesthesia motivated by experimental data. This focus on the neural mechanism in the light of experimental data is the common feature of the topics and the chapters. In addition, the book aims to clarify the shared physiological mechanisms of both phenomena, but also reveal their physiological differences.

Contrary to the popular belief, "Le sommeil n'est plus milieu s(lr" (J. Cocteau, cf. Cl. Gaultier, Pathologie respiratoire du sommeil, La Presse Medicale, 16, 561-563, 1987), and anesthesia is even less safe. Sudden Infant Death Syndrome, Obstructive Sleep Apnea, Ondine's Curse and various respiratory complications of general anesthesia are not so rare; as a matter of fact they happen much too frequently. The idea of organizing another symposium dealing with breathing in sleep and anesthesia has been discussed almost immediately after we said "good bye" to the Organizers of the excellent Paris meeting "The Regulation of Respiration during Sleep and Anesthesia" (R.S. Fitzgerald, H. Gautier, S. Lahiri eds., Advances in Experimental Medicine and Biology, vol. 99, Plenum, New York 1978). Taking into account the impressive amount of data that have emerged during the last few years, we have decided that we shall meet and discuss them; we hoped also that the publication of the scientific material might be useful for everybody interested in the physiology and pathophysiology of breathing, anesthesia and sleep. So we met in Warsaw under the auspices of the European Society for Clinical Respiratory Physiology and the Polish Academy of Sciences, we discussed vividly many fascinating papers presented by our Colleagues from Europe and America and Plenum Press has published the proceedings. I hope that the final result will satisfy the reader.

During the 1976 Fall Meeting of the American Physiological Society Dr. Lahiri and I learned that no plans were being formu lated for holding a symposium on Respiratory Control during the 1977 International Congress. Not to hold such a symposium, we felt, would be the loss of a unique opportunity for us "regula tionists" to exchange ideas viva voce with our international colleagues. It would also break a tradition most recently enjoyed at Srinagar, India in 1974 and at Warsaw, Poland in 1971. After a time-consuming false start we had the good fortune to get advice from Dr. Pierre Dejours to make our plans known to Dr. Henry Gautier. This we did. There resulted an excellent three days of discussion and hospitality at the Faculte de Medecine Saint-Antoine in Paris immediately preceding the International Congress. The aim of the co-chairmen was to gather an international mixture of both the younger and more senior experts to discuss, argue, and maybe even agree on a point or two arising from their current investigations. We wanted to feature, however, recent research trying to determine the influence of sleep and anesthesia on the regulation of respiration. That the sessions were lively and presumably profitable was never more in evidence than when on the second day at 6:15 p.m. after fully nine hours of discussion, argumentation, and some agreement I counted 78 participants still participating.

During sleep and general anesthesia, the brain enters a state of decreased arousal and consciousness is transiently suspended. How this transition occurs is a fundamental and unsolved question in neuroscience. The neural dynamics that disrupt consciousness have not been identified, and the circuit mechanisms that generate these dynamics remain unknown. Furthermore, understanding the neural basis of sleep and anesthesia is key to improving clinical monitoring of patients undergoing general anesthesia and to advancing treatments of sleep disorders and neurological conditions such as coma. In this thesis, I combine intracranial electrophysiology in human subjects with optogenetic manipulation of thalamocortical circuits in mice to identify the neural dynamics underlying sleep and anesthesia. I first show that loss of consciousness during propofol general anesthesia is associated with the abrupt onset of slow oscillations that disrupt cortical networks. I then demonstrate that activation of the thalamic reticular nucleus generates slow wave activity and decreases arousal state, identifying a causal mechanism that generates physiological and behavioral signs of sleep. Finally, I study patients undergoing deep general anesthesia at levels corresponding to medically induced coma, and show that this state is marked by local cortical dynamics consistent with impaired cerebral metabolism. Taken together, these results identify a set of neural dynamics associated with unconscious states, and demonstrate specific mechanisms for how they disrupt brain function. These findings provide new insight into the neuroscience of arousal states, and suggest clinical approaches that could improve patient care.
