Blog Post Image: Exercise reorganizes the brain to be more resilient to stress

The researchers found that running prevents the activation of new neurons in response to stress. In sedentary mice, stress activated new neurons in the hippocampus (red and green cell above), but after 6 weeks of running, the stress-induced activation of both new and mature neurons disappeared. The red cells are new neurons and the green cells are activated mature neurons. (Photo courtesy of the Gould laboratory)
