Ramirez, an assistant professor of psychology and brain sciences at the BU College of Arts & Sciences, claims that memory is more like a reconstructive process than a video recording of the past. Memory is changeable, which is both a blessing and a curse: it’s awful if we recall inaccurate information, but it’s fortunate that our brains can naturally alter and update memories to make them less powerful, especially if it’s something traumatic or frightening. The memory networks in the brain’s hippocampus, a cashew-shaped structure that stores sensory and emotional data vital for creating and retrieving memories, are of particular interest to Ramirez’s team. The team is trying to differentiate between positive and negative memories, which will help them rewire the negative memories. Currently, the research has been conducted over rodents. However, researchers are hopeful that this theory will assist them in uncovering solutions for brain-related disorders.
