The long-term goal is to improve research methodologies for study of alertness/attention. in humans by means of evoked responses obtained when stimuli are provides-at high repetition-rates. This will be accomplished further development of new techniques, both computerized. and behavioral, needed to demonstrate effects of attention/alertness under these special stimulus conditions. High stimulus rates invoke b, rain functions not present at lower rates, such as G-waves, and may provide indications of "temporal binding" mechanisms within the cortex. The experiments will show that the improved techniques work appropriately and are better than presently-available methods. The improvements may well lead to new advances because these responses cannot be obtained now. The project will also determine the hardware/software requirements necessary to meet the needs of laboratory researchers who will first use these techniques. This research is health-related because it is likely to provide data, unavailable by any other means, about brain functions that can be affected by both normal aging, as well as by disease (such as Alzheimer's).

长期目标是改进警觉性/注意力研究的研究方法。在人类中，通过高重复率提供刺激时获得的诱发反应。这将通过进一步开发新技术来实现，两种技术都是计算机化的。和行为，需要证明注意力/警觉性在这些特殊刺激条件下的效果。较高的刺激率会激发较低频率下不存在的b，雨功能，如G波，并可能提供大脑皮层内“时间绑定”机制的迹象。 实验结果表明，改进后的方法是可行的，且优于现有的方法。这些改进很可能会带来新的进展，因为现在无法获得这些反应。该项目还将确定满足将首先使用这些技术的实验室研究人员的需要所需的硬件/软件要求。 这项研究与健康有关，因为它很可能提供任何其他方式都无法获得的关于大脑功能的数据，这些数据既可能受到正常衰老的影响，也可能受到疾病(如阿尔茨海默氏症)的影响。
