NONLINEAR MODEL OF HIPPOCAMPUS

前庭眼反射（VOR）的重要性 在主动运动期间稳定视力通常是未被认识到的， 直到病理损害VOR性能足以干扰 动态视力 我们开发了VOR建模技术， 允许临床医生客观地评估患者VOR功能。 在过去的一年里，我们扩展了这些建模技术， 治疗期间的客观监测。 我们引入了一种新的方法， “超级表现”基于运动员的能力，以提高他们的 通过运动疗法获得动态视力。 通过模拟他们的 在治疗过程中，我们能够监测和预测改善 在运动表现中的动态视觉敏锐度。 轻型颅脑 在运动过程中受伤往往表现为视力下降， 通过VOR稳定。 两个职业橄榄球队员 目前正在用我们的建模技术进行测试。 此外该 弗吉尼亚大学对100名运动员进行了一项研究， VOR建模技术。 运动生理学博士论文， 该大学是基于重新测试这些子集的VOR 运动员头部轻微受伤后 我们扩展了对 VOR对人体研究的宽带特性 行走/跑步时。 初步结果描述了一个重要的 VOR低频通道的新角色，我们预计 将导致预防老年人福尔斯跌倒的集中治疗。

The importance of the vestibulo-ocular reflex (VOR) for stabilizing vision during active movements is generally unrecognized, until pathology impairs VOR performance sufficiently to interfere with dynamic visual acuity. We have developed VOR modeling techniques that allow clinicians to evaluate patients VOR function objectively. During the past year, we extended these modeling techniques to include objective monitoring during therapy. We introduced a new measure of "super performance" based on athletes' abilities to improve their dynamic visual acuity through exercise therapy. By modeling their VORs during therapy, we are able to monitor and predict improvements in dynamic visual acuity during athletic performance. Mild head injury during sports performance often shows up as decreased visual stabilization by the VOR. Two professional football tams are currently being tested with our modeling techniques. In addition, the University of Virginia conducted a study of 100 athletes, using our VOR modeling techniques. A doctoral thesis in Exercise Physiology at that university is based on re-testing the VORs of a subset of these athletes after mild head injury. We extended our analysis of the broad-band characteristics of the VOR to studies of human subjects during walking/running. The preliminary results describe an important new role for lower-frequency channels of the VOR, that we anticipate will lead to focused therapy for preventing falls in the elderly.
