Electrical Stimulation of Brain Pleasure Centers
Videoclips of Experiments
By Silvia Helena Cardoso, PhD
The videoclips available below illustrate classical experiments carried out in the laboratory of Prof. James Olds in the sixties, using rats with metallic electrodes implanted permanently into some brain structures (hypothalamus) which were shown to be responsible for pleasure. When electrically stimulated by the animal itself, by means of an electical switch attached to a lever, this caused a prolonged repetition of the so-called self-stimulation behavior.
