Memory Erasing Treatments for Depression?
Reported in the journal of Science, researchers at the University of Texas Southwestern Medical Center reported that depressed mice become more sociable after a memory molecule was deleted from their brain. This suggests that memory erasing treatments could also cease depression in people. The molecule in a region of the brain, known as the reward pathway, was focused on. Deleting this molecule meant the mice were no longer depressed or fearful, even when conditions were set up that normally made them run and hide. After anesthetizing the mice, they injected a virus into this particular part of the brain and disabled the molecule.
