The New York Times (8/24, Reynolds) reports in its “Well” blog that a 2014 study on mice suggested that exercise might have detrimental effects on long-term memory. Meanwhile, in a new study published in The Journal of Neuroscience “researchers decided to replicate aspects of the 2014 mouse experiment but instead use rats” because research has shown rat brains “are more similar to our brains.” The new study found that rats that exercised displayed long-term memory as good as sedentary rats and had developed “about twice as many new cells as did the brains of the sedentary animals.”
