Stressful Situations Limit the Lifespan of New Neurons

Dr. Daniel Peterson and colleagues used Stereo Investigator to show that stress kills newly generated neurons in the dentate gyrus, an important brain region involved in learning and memory. This study shows the physical impact of social interactions on brain function and metabolism—giving a whole new meaning to the phrase “cellular insult”.

According to Dr. Peterson, “I would not be able to have done the work without MBF’s confocal stereology”
