To date, invasive brain\u2013computer interface (BCI) research has largely focused on replacing lost limb functions using signals from the hand\/arm areas of motor cortex. However, the oculomotor system may be better suited to BCI applications involving rapid serial selection from spatial targets, such as choosing from a set of possible words displayed on a computer screen in an augmentative and alternative communication (AAC) application. Here we aimed to demonstrate the feasibility of a BCI utilizing the oculomotor system.\n                    <jats:italic>Approach<\/jats:italic>\n                    . We developed a chronic intracortical BCI in monkeys to decode intended saccadic eye movement direction using activity from multiple frontal cortical areas.\n                    <jats:italic>Main results<\/jats:italic>\n                    . Intended saccade direction could be decoded in real time with high accuracy, particularly at contralateral locations. Accurate decoding was evident even at the beginning of the BCI session; no extensive BCI experience was necessary. High-frequency (80\u2013500 Hz) local field potential magnitude provided the best performance, even over spiking activity, thus simplifying future BCI applications. Most of the information came from the frontal and supplementary eye fields, with relatively little contribution from dorsolateral prefrontal cortex.\n                    <jats:italic>Significance<\/jats:italic>\n                    . Our results support the feasibility of high-accuracy intracortical oculomotor BCIs that require little or no practice to operate and may be ideally suited for \u2018point and click\u2019 computer operation as used in most current AAC systems.\n                  <\/jats:p>","DOI":"10.1088\/1741-2552\/aa5a3e","type":"journal-article","created":{"date-parts":[[2017,1,18]],"date-time":"2017-01-18T11:48:18Z","timestamp":1484740098000},"page":"046007","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":15,"title":["Decoding of intended saccade direction in an oculomotor brain\u2013computer interface"],"prefix":"10.1088","volume":"14","author":[{"given":"Nan","family":"Jia","sequence":"first","affiliation":[{"name":"Boston University"},{"name":"Boston University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Scott L","family":"Brincat","sequence":"additional","affiliation":[{"name":"Massachusetts Institute of Technology"},{"name":"Massachusetts Institute of Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andr\u00e9s F","family":"Salazar-G\u00f3mez","sequence":"additional","affiliation":[{"name":"Boston University"},{"name":"Boston University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mikhail","family":"Panko","sequence":"additional","affiliation":[{"name":"Boston University"},{"name":"Boston University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frank H","family":"Guenther","sequence":"additional","affiliation":[{"name":"Boston University"},{"name":"Massachusetts Institute of Technology"},{"name":"Boston University"},{"name":"Boston University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Earl K","family":"Miller","sequence":"additional","affiliation":[{"name":"Massachusetts Institute of Technology"},{"name":"Massachusetts Institute of Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2017,5,17]]},"reference":[{"key":"jneaa5a3ebib001","doi-asserted-by":"publisher","first-page":"141","DOI":"10.1038\/416141a","type":"journal-article","article-title":"Instant neural control of a movement signal","volume":"416","author":"Serruya","year":"2002","journal-title":"Nature"},{"key":"jneaa5a3ebib002","doi-asserted-by":"publisher","first-page":"1829","DOI":"10.1126\/science.1070291","type":"journal-article","article-title":"Direct cortical control of 3D neuroprosthetic devices","volume":"296","author":"Taylor","year":"2002","journal-title":"Science"},{"key":"jneaa5a3ebib003","doi-asserted-by":"publisher","first-page":"E42","DOI":"10.1371\/journal.pbio.0000042","type":"journal-article","article-title":"Learning to control a brain\u2013machine interface for reaching and grasping by primates","volume":"1","author":"Carmena","year":"2003","journal-title":"PLoS Biol."},{"key":"jneaa5a3ebib004","doi-asserted-by":"publisher","first-page":"1098","DOI":"10.1038\/nature06996","type":"journal-article","article-title":"Cortical control of a prosthetic arm for self-feeding","volume":"453","author":"Velliste","year":"2008","journal-title":"Nature"},{"key":"jneaa5a3ebib005","doi-asserted-by":"publisher","first-page":"210ra154","DOI":"10.1126\/scitranslmed.3006159","type":"journal-article","article-title":"A brain\u2013machine interface enables bimanual arm movements in monkeys","volume":"5","author":"Ifft","year":"2013","journal-title":"Sci.
