People who include a little yoga or Tai Chi in their day may be more likely to remember where they put their keys. Researchers at the University of California, Irvine (UCI) and Japan’s University of Tsukuba found that even very light work-outs can increase the connectivity between parts of the brain responsible for e memory formation and storage.
In a study of 36 healthy young adults, the researchers discovered that a single 10-minute period of mild exertion can yield considerable cognitive benefits. Using high-resolution functional magnetic resonance imaging, the team examined subjects’ brains shortly after exercise sessions and saw better connectivity between the hippocampal dentate gyrus and cortical areas linked to detailed memory processing.
Their results were published in the journal Proceedings of the National Academy of Sciences. “The hippocampus is critical for the creation of new memories; it’s one of the first regions of the brain to deteriorate as we get older – and much more severely in Alzheimer’s disease,” said Project Co-leader Michael Yassa, UCI professor and Chancellor’s Fellow of neurobiology & behavior. “Improving the function of the hippocampus holds much promise for improving memory in everyday settings.”
The neuroscientists found that the level of heightened connectivity predicted the degree of recall enhancement.
Yassa, director of UCI’s Center for the Neurobiology of Learning and Memory and the recently launched UCI Brain Initiative, said that while prior research has centered on the way exercises promote the generation of new brain cells in memory regions, this new study demonstrates a more immediate impact: strengthened communication between memory-focused parts of the brain.
“We don’t discount the possibility that new cells are being born, but that’s a process that takes a bit longer to unfold,” he said. “What we observed is that these 10-minute periods of exercise showed results immediately afterward.”
