A modification of the self-stimulation technique of Olds enabled rats to regulate and maintain at a preferred level the amount of brain-stimulating current they received as reinforcement for lever pressing. The method used two levers to deliver brief brain shocks: each response at one lever increased the current intensity a small step and each response at the other lowered it one step.
