New research published in The Journal of Neuroscience demonstrates that the cognitive benefits of physical exercise can be transmitted transgenerationally from grandfathers to grandsons, suggesting that exercise-induced cognitive improvements may persist across multiple generations. Exercise has been shown to enhance neuroplasticity and improve cognitive abilities in various species, including humans. Previous research has explored the intergenerational transmission of these benefits, particularly from parents to their offspring. However, the extent to which these effects can be transmitted be…
