London: The study led by Cambridge University showed that running triggered the growth of hundreds of thousands of new brain cells in a region that is linked to the formation and recollection of memories.
They were then subjected to a memory test where the more they nudged the correct square, the better they scored. The findings revealed that the running mice scored nearly twice as high as the control group during the memory test. However, the greatest improvement occurred in the later stages of the experiment, when the two squares were so close they nearly touched. “At this stage of the experiment, the two memories the mice are forming of the squares are very similar,” Bussey said. “It is when they have to distinguish between the two that these new brain cells really make a difference,” he added.
