Fish on Prozac: effect of serotonin reuptake inhibitors on cognition in goldfish.

The authors studied the effect of fluoxetine (a specific serotonin reuptake inhibitor--SSRI) on active avoidance learning in fish. In an active, two-way, shuttle-box avoidance task we compared escape and avoidance of shock among fish receiving chronic administration of fluoxetine (Prozac), others receiving a 5-HT(1A) receptor antagonist (WAY 100,635; Sigma, St. Louis, MO) and controls.
