Computer simulations explain the limitations of working memory

[PRESS RELEASE, 31 March 2009] Researchers at the Swedish medical university Karolinska Institutet (KI) have constructed a mathematical activity model of the brain's frontal and parietal parts, to increase the understanding of the capacity of the working memory and of how the billions of neurons ...

Virtual reality: Keyhole surgeons training could help meet European working time directives
