  "Description": "A fast, interactive cross-platform, and easy to share\n'WebGL'-based 3D brain viewer that visualizes 'FreeSurfer'\nand/or 'AFNI/SUMA' surfaces. The viewer widget can be either\nstandalone or embedded into 'R-shiny' applications. The\nstandalone version only require a web browser with 'WebGL2'\nsupport (for example, 'Chrome', 'Firefox', 'Safari'), and can\nbe inserted into any websites. The 'R-shiny' support allows the\n3D viewer to be dynamically generated from reactive user\ninputs. Please check the publication by Wang, Magnotti, Zhang,\nand Beauchamp (2023, <doi:10.1523/ENEURO.0328-23.2023>) for\nelectrode localization. This viewer has been fully adopted by\n'RAVE' <https://rave.wiki>, an interactive toolbox to analyze\n'iEEG' data by Magnotti, Wang, and Beauchamp (2020,\n<doi:10.1016/j.neuroimage.2020.117341>). Please check\ncitation(\"threeBrain\") for details.",
