Terry Sejnowski is truly astonished by this finding as he states the following: In order to reach their breakthrough discovery, the researchers built a 3D reconstruction of rat hippocampus tissue, which happens to be the memory center of the brain. In doing so, they were able to stumble across one of the most interesting findings in a very long time; the synapses, or the junctions that form between neurons which are used to send messages to the brain, were being duplicated in about 10 percent of cases. According to Tom Bartol, another scientist belonging to the group, has stated the following: In order to help you better understand what the scientists did, there is a video below so make sure that you watch that and gain a heightened sense of fascination of what your brain is capable of doing.
