| Abstract: | To obtain a better understanding of how well the Y-maze preference test paradigm indexes electrical brain stimulation reward, the present experiment compared the abilities of this rate-independent paradigm and a rate-dependent paradigm to assess the rewarding effectiveness of brain stimulation. The rate-dependent paradigm used was an operant chamber. The results showed that over a wide range of stimulation parameters the rate-independent paradigm provided a better assessment of the rewarding effectiveness of the brain stimulation than did the rate-dependent paradigm. |
