The article reports on the study about the act of recalling a memory conducted by researchers at the University of Pennsylvania and Princeton University in the U.S. The research discovers the valuable use of functional magnetic resonance imaging, a form of magnetic resonance imaging of the brain that registers blood flow to functioning areas of the brain. Such breakthrough manifests that retention recovery is like reminiscing the past for memories that are forgotten can be restored by the memory system. In fact, according to Sean Polyn of Pennsylvania Computational Memory Lab, a daily scheme for capturing lost memories demands the use of a portion of a memory to extract the complete idea.
