Eso significa que una familia podría recibir la noticia de que su ser querido responde cuando en realidad el método está viendo ruido. Detrás de cada falso positivo hay decisiones médicas y expectativas que se construyen sobre algo que no existe. Antes de creer en un \"sí\" en la pantalla, conviene preguntar cuánto se equivoca la máquina.","quienFirma":"medRxiv (preprint de investigación clínica)","confianza":"preprint","consulta":{"pregunta":"¿Confiarías en un test que dice que alguien en coma responde?"}},"sello":{"hash":"f91687a6f15ada0f54a6c3d9a50746a9c4470017be76d2a188998d4c005d26be","sello":"206cefa22040b916fc12a4eb35e988255a3ef829d9c4d0037c8537abb6854dcf","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6613902,"aleatorio":"ac82709ad8e3a4bd05e61ae8db26b91730bcd6360b48b2bfeb8599155701938c","tiempo":"2026-11-05T03:08:00.000Z"},"nist":{"cadena":2,"pulso":2013885,"salida":"4BC0B9AEE35F891E049625C3E1197C382F83B5FAE9D6FA1BA260D56A9D8EF2180A02CD7F22A59A00EDA42EDB618EEBCEA51E10B3B7C97010EEA4E68681A8A82F","tiempo":"2026-11-05T03:07:00.000Z"},"noAntes":"2026-11-05T03:08:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Nov  5 03:08:36 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"False-Positive Calls of Reimplemented Published Analyses for Covert Command-Following on Electroencephalograms Recorded Without Study Commands","descripcion":"Objective: To measure how often published electroencephalographic analyses for covert command-following call patients positive without commands, and their detection of genuine responses.
