Esto ayuda a entender por qué personas con daño en esa zona tienen dificultades para generalizar lo aprendido. Para cualquiera que estudie o aprenda algo nuevo, es una pista de que los detalles no sobran.

Recent work has proposed that some forms of semantic knowledge could be encoded in low-dimensional neural representations, such as the abstract, disentangled representational geometries observed in many cognitive brain areas. Experimental work has shown that hippocampal (HPC) lesions impair the formation of flexible and generalizable semantic knowledge. However, HPC representations are often high-dimensional and sparse. How can these representations contribute to the formation of low-dimensional abstract representation across these cognitive cortical areas? Here, we reconcile these observations using multiregional neura","pubDate":"2026-10-26","url":"https://www.biorxiv.org/content/10.64898/2026.10.24.761577v1?rss=1"},"indexado":"2026-10-26T13:37:38.955Z"}}
