Esto permite que los estudios hechos en monos sirvan mejor para explicar nuestra propia mente. Para cualquiera que piensa en cómo aprende o predice, es una pista de que esa capacidad es más antigua de lo que parece. Lo que todavía no está claro es si las mediciones de sangre reflejan siempre lo que pasa en las neuronas, y ese es el límite serio del trabajo.","quienFirma":"Universidad (investigación en neurociencia, bioRxiv)","confianza":"preprint","consulta":null},"sello":{"hash":"8d6c92393733ff9cf97961ed03015da51e9299f93f191cdc6730082587e1e269","sello":"c5ee496c4d404b031101cab06e8812ec2c6178bae60acfe2a73aa59de19dbea9","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6589233,"aleatorio":"9e3771ddc58969f14f5a222bb9b7094431610becfbf31158b3d02257e478abf8","tiempo":"2026-10-27T13:33:30.000Z"},"nist":{"cadena":2,"pulso":2001772,"salida":"0E703280D2ECB99CF237148891BE4B05125CA4A9FA93BA99C93DE108693398FC1C1436A917C2E942D3FD99D4FACCDDC40E70589522F4EEDE9B18514294B0BD55","tiempo":"2026-10-27T12:55:00.000Z"},"noAntes":"2026-10-27T13:33:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 27 13:33:55 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Linking cross-species hemodynamics with neuronal activity in prefrontal cortex during abstract sequence viewing","descripcion":"The ability to identify and predict abstract sequential patterns enables a wide range of complex cognition and behavior, but the mechanisms mediating it remain poorly understood. Lateral prefrontal cortex (LPFC) has been implicated in abstract sequence tracking in both humans and macaques, but it is unclear whether underlying processes are shared across species. Furthermore, most existing evidence relies on hemodynamic responses, which can have variable relationships with neuronal activity in a region. We leverage a combination of human fMRI, monkey fMRI, and monkey electrophysiology to bridge these gaps. We find that humans and non-human primates show functionally homologous hemodynamic act","pubDate":"2026-10-27","url":"https://www.biorxiv.org/content/10.64898/2026.10.23.761183v1?rss=1"},"indexado":"2026-10-27T13:32:50.787Z"}}
