Somnology Somnology Somnology is the scientific study of sleep. It includes clinical study and treatment of sleep disorders and irregularities. Sleep medicine is a subset of somnology. After the invention of the EEG, the stages of sleep were determined in 1936 by Harvey and Loomis, the first descriptions of delta and theta waves were made by Walter and Dovey, and REM sleep was discovered in 1953. Sleep apnea was identified in 1965. In 1970, the first clinical sleep laboratory was developed at Stanford. The first actigraphy device was made in 1978 by Krupke, and continuous positive airway pressure therapy and uvulopalatopharyngoplasty
Methods used to study memory conditioning. This type of research is extremely useful and has shed much light on learning and memory in humans. Scientific reductionism has pushed our understanding of memory closer to the neural level. In order to broaden our understanding, we need to draw conclusions from converging evidence. Studying memory in animals such as birds, rodents, and primates is difficult because scientists can only study and quantify observable behaviors. Animal research relies on carefully constructed methodologies, and these are species specific. A major obstacle to research on the innateness of memory is the scarcity of subjects with apparent superior memory quality to
