From an observational science it developed a systematic way of approaching the nervous system and possible interventions in neurological disease. ==Early history== An ancient Egyptian treatise concerning trauma surgery, the Edwin Smith papyrus, contains descriptions and suggests treatments for various injuries, including some of neurological nature. Specifically, there are descriptions of the meninges, the external surface of the brain, the cerebrospinal fluid and the intracranial pulsations.〔Wilkins, 1964〕 Not only are these neurological features mentioned, but it is also noticed that some bodily functions can be impaired by brain injuries or injuries to the cervical spine.〔 There are many other examples of observations of neurological phenomena throughout history. The Sumerians illustrated paraplegia caused by physical trauma in a bas relief of a lion with an arrow in its back.〔Paulissian, 1991 p.35〕 Neurological disorders not caused by physical disorder were also investigated. For example in the medicine of the Vedic period of ancient India, the Ayurvedic text Charaka Samhita discusses epilepsy, with a discussion of both symptoms and of possible treatments. Slightly later, the ancient Greek physician Hippocrates was convinced that epilepsy has a natural cause, not a sacred one.〔World Health Organization, Fact Sheet #168〕 The ancient Greeks also dissected the nervous system. For example, Aristotle (although he misunderstood the function of the brain) describes the meninges and also distinguishes between the cerebrum and the cerebellum.〔von Staden, p.157〕 Slightly later, in Rome, Galen performed many dissections of the nervous system in a variety of species, including the ape. One particular discovery he made was of the importance of the recurrent laryngeal nerves. Originally, he cut through them accidentally while performing an experiment on the nerves that control breathing by vivisection of a strapped-down, squealing pig. The pig immediately stopped squealing, but continued struggling. Galen then performed the same experiment on a variety of animals, including dogs, goats, bears, lions, cows and monkeys, finding similar results each time. Finally, to publicise this new result, Galen demonstrated the experiment on a pair of pigs to a large audience in Rome, telling them: "there is a hairlike pair (nerves ) in the muscles of the larynx on both left and right, which if ligated or cut render the animal speechless without damaging either its life or functional activity"〔Gross, 1998〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「History of neurology」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
