Discussion:Striatum

From Wikipedia, the free encyclopedia

Surprenante découverte au sujet du striatum.

Until a few years ago, it was believed that the prefrontal cortex learns information quickly, then sends what it learns to the basal ganglia, which helps form habits, such as the ability to play a musical instrument. However, in 2005, Miller and colleagues showed that when monkeys learn simple tasks, their basal ganglia are more active early in the process, followed by a slower activation in the prefrontal cortex.

In other words, the striatum quickly learns the individual puzzle pieces, and the prefrontal cortex puts them together, Miller says. He and Antzoulatos theorized that the same pattern would be evident during category learning. How the brain assigns objects to categories. New findings may explain why children with autism tend to fixate on details instead of seeing the big picture.--Pierre-Alain Gouanvic Ubuntu! 12 août 2011 à 05:31 (CEST)
