DESCRIPTION (provided by applicant): This K01 application responds to PA-10-056, and is intended to obtain support and "protected time" for Dr. Rajeev I. Desai (PI) to gain extensive supervised research training and experience in all aspects of intravenous (IV) self-administration methodology in non-human primates (NHP). The project is designed to systematically allow the PI to acquire necessary skills and experience to independently and expertly study the reinforcing effects of stimulant and other addictive drugs, and to couple this methodology with concurrent in vivo microdialysis to measure related neurochemical activity. The support provided by the K01 award will ultimately allow the PI to: a) develop a comprehensive program of highly translational neurochemical and behavioral studies to directly address the public health concern of stimulant addiction and the development of medications for its treatment; and b) acquire the tools necessary to independently continue and expand this line of research through R01 funding mechanisms. The aims of this project are designed to optimize the PI's training experience through a systematic series of experiments evaluating IV cocaine and nicotine self- administration behavior under simple and complex schedules of reinforcement. The PI next will couple his existing expertise with in vivo microdialysis techniques to his newly acquired behavioral skills to measure changes in striatal dopamine levels produced by cocaine and nicotine during IV self-administration performance under different schedule conditions. Finally, studies will be conducted to determine whether nicotinic agonist-based candidate medications attenuate reinforcing and neurochemical effects of self- administered nicotine or cocaine. The proposed research in this project will establish the PI as a well-trained and independent young scientist who is qualified to conduct highly translational addiction research in NHP. In addition, the planned studies may lead to the further development of promising novel nicotinic-based pharmacotherapy to help combat the scourge of stimulant addiction that plagues our public health.

描述（由申请人提供）：本K01申请响应PA-10-056，旨在为Rajeev I. Desai博士（PI）获得支持和“保护时间”，以获得广泛的监督研究培训和非人类灵长类动物（NHP）静脉注射（IV）自我给药方法各方面的经验。该项目旨在系统地让PI获得必要的技能和经验，以独立和专业地研究兴奋剂和其他成瘾药物的强化作用，并将这种方法与体内微透析相结合，以测量相关的神经化学活动。K01奖提供的支持最终将使PI能够：a)制定一个高度转化的神经化学和行为研究的综合计划，以直接解决兴奋剂成瘾的公共卫生问题和治疗药物的开发；b)获得必要的工具，通过R01资助机制独立地继续和扩大这条研究线。本项目旨在通过系统的一系列实验来评估IV可卡因和尼古丁在简单和复杂强化计划下的自我给药行为，从而优化PI的培训体验。PI接下来将把他现有的专业知识与体内微透析技术结合起来
