Brain Stimulation Reward

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.

Famous quotes containing the words reward, brain and/or stimulation:

    But whenever you pray, go into your room and shut the door and pray to your Father who is in secret; and your Father who sees in secret will reward you.
    Bible: New Testament, Matthew 6:6.


    I consider that a man’s brain originally is like a little empty attic, and you have to stock it with such furniture as you choose.
    Sir Arthur Conan Doyle (1859–1930)

    The lore of our fathers is a fabric of sentences. In our hands it develops and changes, through more or less arbitrary and deliberate revisions and additions of our own, more or less directly occasioned by the continuing stimulation of our sense organs. It is a pale gray lore, black with fact and white with convention. But I have found no substantial reasons for concluding that there are any quite black threads in it, or any white ones.
    Willard Van Orman Quine (b. 1908)
