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 Indiana Alcohol Research Center (IARC) is in its 18th year, and the Alcohol Research Lab of the GCRC continues to pursue knowledge of the association between the brain's response to alcohol and genetic influences on the risk for alcohol dependence. With a good track record of controlling the magnitude of the exposure to alcohol (breath alcohol concentration, BrAC), the current project seeks to test the hypothesis that a family history of alcoholism (FHA) is also associated with how fast the brain is exposed to alcohol (the rate of change of BrAC with respect to time, slope). With GCRC support, we have now successfully completed development of a protocol that permits the slope of brain exposure to alcohol be controlled precisely on both ascending and descending limbs. In this study, that protocol will be employed to examine 60 subjects (split by FHA, balanced by gender and spanning a substantial range of recent drinking history (RDH)). Each will undertake 2 alcohol infusion sessions, providing records of electrophysiological and subjective responses to alcohol that will be examined at 3 critical points for evidence of the postulated primary association with FHA.

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。子项目和 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。 印第安纳州酒精研究中心（IARC）已经成立18年了，GCRC的酒精研究实验室继续探索大脑对酒精的反应与酒精依赖风险的遗传影响之间的关联。 在控制酒精暴露量（呼吸酒精浓度，BrAC）方面有着良好的记录，目前的项目旨在测试酒精中毒家族史（FHA）也与大脑暴露于酒精的速度（BrAC相对于时间的变化率，斜率）相关的假设。 在GCRC的支持下，我们现在已经成功地完成了一项协议的开发，该协议允许在上升和下降肢体上精确控制大脑暴露于酒精的斜率。 在本研究中，将采用该方案检查60名受试者（按FHA划分，按性别平衡，并跨越近期饮酒史（RDH）的大范围）。 每名受试者将接受2次酒精输注，提供对酒精的电生理和主观反应记录，并在3个关键点检查这些记录，以获得假定的主要与FHA相关的证据。
