Brain stimulation reward

（重定向自Intracranial self stimulation）

brain stimulation, not pictured, seeks to replicate the effects of completely natural reward stimulation, as shown here

Brain stimulation reward (BSR) is a phenomenon in which direct stimulation of regions of the brain through either electrical or chemical means is rewarding and can serve as an operant reinforcer. The stimulation activates the reward system and establishes response habits similar to those established by natural rewards such as food and water. BSR experiments soon demonstrated that stimulation of the lateral hypothalamus and other regions of the brain associated with natural reward was both rewarding as well as drive inducing. Electrical brain stimulation and intracranial drug injections are among the most powerful rewards because they activate the reward circuitry directly rather than through the peripheral nerves. BSR has been found in all vertebrates tested, including humans, and it has provided a useful tool for understanding how natural rewards are processed by the brain as well as the anatomical structures and the neurochemistry associated with the brain's reward system.
