DESCRIPTION (provided by applicant): Alcohol abuse can degrade health, cause accidents and reduce productivity. Alcohol consumption can cause acute behavioral slowing and difficulties in concentrating and sustaining attention. Since the relation between blood alcohol and behavioral impairment differs across individuals, increased understanding of the functional impact of alcohol might be obtained through more direct assessment of the effect of alcohol on the human brain. At present there is no convenient way to gauge the effect of alcohol on brain activity, especially in individuals performing real world tasks or approximations thereof such as simulated driving or flight. Recent technological and scientific advances imply the feasibility of a breakthrough technology, the Neurolyzer, specifically designed for routine, automated measurement of the brain's response to alcohol during complex task performance. Similar to blood-breath alcohol meters, such as the Breathalyzer, that gauge the amount of alcohol consumed, the Neurolyzer will provide a continuous index of the effect of alcohol on the brain. It will be embodied in a low-cost, highly automated turnkey system for recording and analyzing the impact of alcohol on EEG signals, that outputs a continuously updated index of the neuromodulatory effects of alcohol. It will embody accumulated expertise about analysis of EEG signals into automated software that will reduce the labor required to extract such information by orders of magnitude, making direct measurements of brain activity available to alcohol researchers conveniently and inexpensively. Building on past successful projects, Phase I will evaluate key remaining scientific and signal processing issues. If successful, Phase II would produce and evaluate a system capable of monitoring an intoxicated individual while he or she engages in complex activities, enabling systematic study of the neural effects of alcohol in contexts ranging from refined laboratory tasks to simulations of real world activities to social interactions. Because the family of devices to which the Neurolyzer will be added has application in many areas beyond alcohol research, the project has good prospects for commercial success.

描述（由申请人提供）：酗酒会损害健康、导致事故并降低生产力。饮酒会导致严重的行为迟缓以及难以集中和维持注意力。由于血液酒精与行为障碍之间的关系因人而异，因此可以通过更直接地评估酒精对人脑的影响来加深对酒精功能影响的了解。目前还没有方便的方法来衡量酒精对大脑活动的影响，特别是对于执行现实世界任务或类似任务（例如模拟驾驶或飞行）的个体。最近的技术和科学进步意味着突破性技术的可行性，即 Neurolyzer，专门设计用于在执行复杂任务时对大脑对酒精的反应进行常规、自动测量。与测量酒精消耗量的血液呼吸酒精测量仪（例如呼吸分析仪）类似，神经分析仪将提供酒精对大脑影响的连续指数。它将体现在一个低成本、高度自动化的交钥匙系统中，用于记录和分析酒精对脑电图信号的影响，输出不断更新的酒精神经调节作用指数。它将把脑电图信号分析方面积累的专业知识融入到自动化软件中，从而将提取此类信息所需的劳动力减少几个数量级，从而使酒精研究人员能够方便且廉价地直接测量大脑活动。在过去成功项目的基础上，第一阶段将评估剩余的关键科学和信号处理问题。如果成功，第二阶段将生产和评估一个能够在醉酒个体从事复杂活动时对其进行监测的系统，从而能够在从精致的实验室任务到模拟现实世界活动到社交活动的背景下系统地研究酒精的神经影响。互动。由于将添加 Neurolyzer 的设备系列在酒精研究以外的许多领域都有应用，因此该项目具有良好的商业成功前景。
