Quizplus · Accepted Answer

Rats have been found to choose to repeatedly self-stimulate their brain's pleasure centers (such as the nucleus accumbens) through implanted electrodes, even over natural rewards like food, water or sex. This behavior is known as "intracranial self-stimulation" or ICSS and is often used as a model to study the neural basis of addiction and motivation.
