Olfactory bulbectomy

This model mimics behavioral, physiological and neurochemical features of depression, such as deficits in learning and memory, reduced food motivated behavior and libido, and stress hyper-responsiveness. Bulbectomised animals show impairment of cognitive function. This animal model resembles the agitated depression phenomena found in humans. This model is applicable for both rats and mice.

After 14 days, OB mice display characteristic open field hyperactivity, which is reversed by paroxetine or paroxetine plus WAY 100635. Data represent means with SE.
