Brain stimulation reward papers 2

Brain stimulation reward (BSR) research seems focused mainly on understanding the anatomy, chemical contingiencies and optimal stimulation parameters of the circuit, and less on developing operant conditioning protocols. Authors like Burgess et al (1991), Garner et al (1991), Talwar et al (2002), Hermer-Vasquez et al (2005), who use BSR to generate specific, useful behaviors, are, at the moment, in minority. The limits and potential usefulness of complex operational conditioning by BSR remain largely unexplored.
