Somnology
scientific study of sleep
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. Hypnology has a similar meaning but includes hypnotic phenomena.
History
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 were created in 1981.
The Examination Committee of the Association of Sleep Disorders Centers, which is now the American Academy of Sleep Medicine, was established in 1978 and administered the sleep administration test until 1990. In 1989, the American Board of Sleep Medicine was created to administer the tests and eventually assumed all the duties of the Examination committee in 1991.
Begin with the source’s own compact description: “Somnology” is scientific study of sleep. The dossier treats that line as a proposition to test through Somnology, scientific and study, not as a finished interpretation.
Why this record matters
The phrase “scientific study of sleep” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Nov 18, 2024. The linked authority identifier is Q1752583. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1936, 1953, 1965 and 1970.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
