"Development of the rat P300 ERP during backward chaining"
Several experiments in our laboratory shown P300 amplitude to be an incremental function of proximity to conditioned reinforcers in simple behavioral chains. In this paradigm, one tone predicts lever insertion while a ...
Analysis of mRNA changes as a function of learning and methamphetamine exposure
Methamphetamine is a powerful, addictive drug that is of great concern in Iowa and the Midwest. Powerful methamphetamine abuse is correlated with depression and learning disabilities (e.g. attention deficit disorder). ...
The Development of the P300 event related potential in rats during the initial stages of shaping lever pressing
Several experiments in our laboratory have shown that P300 ERP amplitude in rats is a decremental function of conditioned stimulus proximity to primary reinforcement in behavioral chains. We have also demonstrated robust ...
"The Effects of methamphetamine and cocaine on rats' Y-Maze performance using directional vs. visual cues"
Two experiments in our laboratory have demonstrated that across a wide range of doses, amphetamine but not cocaine (COC) disrupts the discrimination performance of rats running toward the lighted arm of a Y-Maze. In these ...
"The rat P300 ERP to signaled occurrence and omission of expected reinforcers following extended training"
A series of experiments in our laboratory have shown that rat P300 ERP amplitude is an incremental function of conditioned stimulus proximity to primary reinforcement in simple behavioral chains, suggesting that the P300 ...
