BRAIN METABOLIC RESPONSE TO COCAINE CUE IN COCAINE USERS

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目及 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 该研究的目的是观察大脑功能是否被激活（如PET扫描所证明的），同时观看参与药物使用和药物相关行为的人的视频，以及当受试者受到哌醋甲酯挑战时，这些激活是否显示增加。研究人员将这些反应与受试者在类似条件下观看中性场景的视频时的反应进行比较。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The goal of the study is to see if brain function becomes activated (as evidenced by PET scans) while viewing a video of people involved in drug use and drug-related behavior and whether those activations show an increase when subjects are challenged with methylphenidate compared to when they are not. The researchers will compare those responses to that of when subjects watch a video of neutral scenes under similar conditions.
