Advanced neuroimaging reveals how a short workout can trigger increased activity and communication between neurons in the brain's memory center.Iowa City TodayNew research from the University of Iowa suggests that a short workout can rewire the brain and improve memory. While previous studies have shown a link between exercise and brain health, this latest research provides a real-time look at how exercise directly impacts the activity of neurons in the hippocampus, the part of the brain responsible for memory.
Why it matters
This study offers valuable insights into how lifestyle choices, particularly physical activity, can support brain function over time. Understanding the direct neurological benefits of exercise could lead to new therapies and interventions to improve memory and cognitive abilities.
The details
The study, led by neuroscience professor Michelle Voss, PhD, used advanced imaging techniques to track the activity of neurons in the hippocampus during and after exercise. The researchers found that moderate exercise a few times a week can increase the size of the hippocampus and that the timing of the exercise can make a difference in how memory is consolidated.
- The study was published on April 6, 2026.
