Brain's Cache Memory Found

Shipud writes "Electrical activity in a single section of the brain has been linked to very short-term working memory, as is reported at Nature. Very short-term working memory capacity is thought to be related to intelligence. In the same way that a larger cache speeds processing time, people with a greater capacity for holding images in their heads are expected to have better reasoning and problem-solving skills. The localization of this ability is a surprising finding, as until now it was believed that STWM was diffused throughout the cortex, rather than localized."
