REVISIÓN DE ELECTROENCEFALOGRAFÍA PORTABLE Y SU APLICABILIDAD EN NEUROCIENCIAS.

Encephalography is a technique that allows the recording of electrical activity of the brain and has been studied during the last hundred years in different areas of neuroscience. For several years, measuring equipment that are portable and that allow a good signal quality to have been researched and developed, so a literature review of the manufacturing companies of some of portable electroencephalography devices available on the market was carried out: Its main features are exposed, as well as some of the work found that were made with those, comparisons between them and a discussion about the advantages and disadvantages of their features. It is concluded that, when a portable encephalography device is bought, it's necessary to take into consideration the use that it will be having and the cost-benefit that the device has according to its features.
