ECoG has greater amplitude, higher topographical resolution, and a much broader frequency range than scalp-recorded electroencephalography and is less susceptible to artifacts. With current and foreseeable recording methodologies, ECoG is likely to have greater long-term stability than intracortically recorded signals. Furthermore, it can more readily be recorded from larger cortical areas, and it requires much lower digitization rates, thus greatly reducing the power requirements of wholly implanted systems.10abrain signals10abrain-computer interfaces10aECoG10aintracortically recorded signals1 aWolpaw, Jonathan1 aWinter-Wolpaw, E1 aSchalk, Gerwin  uhttp://www.oxfordscholarship.com/view/10.1093/acprof:oso/9780195388855.001.0001/acprof-9780195388855-chapter-01500504nas a2200157   4500008004100000022001900041245004000060210003900100260002800139100001900167700001300186700002000199700002100219700002100240856008500261       2012                        eng d  a978-019538885500aHardware and Software Technologies.0 aHardware and Software Technologies  bOxford University Press1 aSchalk, Gerwin1 aGuger, C1 aWilson, Adam, J1 aWolpaw, Jonathan1 aWinter-Wolpaw, E  uhttps://neurotechcenter.org/publications/2012/hardware-and-software-technologies
