Exercise Aids Memory Erasure in PTSD

Increased neuron formation in the hippocampus, stimulated by exercise or genetic manipulation, helps mice forget traumatic or drug-associated memories. This process involves rewiring neural circuits, disrupting the recall of fear memories. These findings offer potential new approaches for treating mental health conditions like PTSD and drug addiction.
