Activation of the Prefrontal Cortex Improves Working Memory

Working memory or short-term memory is related to the ability to pass intelligence tests and is stored in the parietal cortex. However, the role of other areas of the cortex which are activated during use of visual memory is poorly understood. An IDIBAPS team has programmed a complex virtual system that simulates a network of neurons, according to which the prefrontal cortex reinforces the activation of the parietal cortex. This makes is possible to increase the working-memory capacity when necessary. This hypothesis is confirmed by functional magnetic resonance data.
