Registraron neuronas en un área clave del canto y encontraron que allí se mezclan las señales de voz y de movimiento.","fuente":"biorxiv","fuenteNombre":"bioRxiv · preprints","color":"#be2628","autor":"Jones, C., Teoh, H.

En su cerebro, las neuronas responden a ambas cosas a la vez. Para una persona de acá, esto muestra que la comunicación con voz y cuerpo juntos, algo tan humano, tiene raíces en el aprendizaje social de otras especies. El estudio se hizo en aves, así que las comparaciones con el lenguaje humano son indirectas.","quienFirma":"bioRxiv (preprint, sin revisión por pares)","confianza":"preprint","consulta":{"pregunta":"¿Un animal puede aprender a comunicarse como una persona?"}},"sello":{"hash":"81aa5c52d75bbb5b3cb24ecc32c8829a890df30548f14ccba2940de175b009bd","sello":"7f120b0637b2c9e836eb0c0435f96827fc5956481dc33f74603651c8877cfeb8","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6574484,"aleatorio":"17f8dc6691055e17d3340945fc697b1d14385d774dc400926b289d0664c160fb","tiempo":"2026-10-22T10:39:00.000Z"},"nist":{"cadena":2,"pulso":1994441,"salida":"917B00588BBAF41DD8C461E7D93EA47DC73C00983776285722380061C2505D68D1C49D178A1E9E1A422EEA35DB6367141AB79828DD0F9592CE1805F752B02469","tiempo":"2026-10-22T10:32:00.000Z"},"noAntes":"2026-10-22T10:39:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 22 10:39:25 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Parrots imitate song and dance with mixed vocal-gestural neural signals","descripcion":"Humans shrug when saying \"I don't know\" and nod when saying \"yes,\" yet it remains unclear how the brain coordinates vocal and gestural motor systems for learned, multimodal communication. Here we find that budgerigar parrots precisely imitate the fine temporal alignment between song and affiliative headbob gestures. Distinct colonies developed unique vocal-gestural motifs, which reorganized into new shared forms following social re-pairing. Neural recordings from the central nucleus of the anterior arcopallium (AAC), the cortical output of the parrot song system, revealed intermixed representations of vocalizations and head kinematics, including mixed selectivity at the level of single neuro","pubDate":"2026-10-22","url":"https://www.biorxiv.org/content/10.64898/2026.10.21.760654v1?rss=1"},"indexado":"2026-10-22T10:38:41.125Z"}}
