(CBS News) Exercise can lower anxiety, but how it does so remains a mystery. Now, a new study conducted at Princeton University, published in the Journal of Neuroscience, may offer clues as to what happens in the brain.
Conducted on mice, the study was done on two groups of the animals. The first group was was given a good amount of exercise and the other was more sedentary. Upon studying their brains, researchers found both groups had formed new brain cells called neurons, but the exercisers formed more neurons that release the neurotransmitter GABA, which has a calming effect on the brain.
