The effects of bilateral, continuous, and chronic Deep Brain Stimulation of the medial forebrain bundle in a rodent model of depression

MFB DBS in the FSL animals selectively affected certain types of behaviors. Exploration and vocalization remained unaltered, but cognitive performance such as speed and precision of memory recall improved compared to unstimulated and stimulated controls. Future studies should focus on the mechanisms of action of MFB DBS, and in particular on the role of dopamine in the stimulation-dependent phenotype changes.
