What experiments did James old perform on rats?

Answer 1

James Olds conducted experiments in the 1950s that involved implanting electrodes in the brains of rats to study their behavior in response to electrical stimulation. He discovered that when the rats were given the ability to self-stimulate specific brain regions, they would repeatedly press a lever to receive the stimulation, often to the exclusion of other activities, such as eating or sleeping. This led to the identification of the brain's "reward system," highlighting the role of certain areas, like the septal area, in motivation and pleasure. His work laid the foundation for understanding the neural mechanisms of reward and addiction.
