项目摘要

DESCRIPTION (provided by applicant): When the brain is injured during development, there is an effect not only on immediate brain function but also on the future ability to learn and acquire skills. We propose to create and simulate multi-scale computational models of the effect of early structural injury on future motor function of the cortex and spinal cord. We will use programmable chips (FPGA's) and the new mathematical theory of "Likelihood Calculus" to build simulations of 300,000 neurons that run 500 times faster than real-time. The model will be fitted to electromyographic and kinematic data from children at two visits spaced one year apart, and predictions will be tested by comparison to a third visit one year later. High speed simulation of the effect of early injury has the potential to revolutionize the treatment of developmental neurological deficits because it can, in one week, simulate 10 years of future change. In doing so, it allows prediction of disease progression, prediction of the future effects of treatments, and detailed understanding of the interaction between brain injury and resulting disorders of movement, perception, and behavior. Because of these predictions, we can intervene much earlier with treatments customized to each patient's disease profile. With early intervention, it may be possible to attenuate or block the natural progression of their disease. With over 750,000 US children and adults affected by developmental brain disorders, early acquired brain injury, or childhood progressive brain disease, the applicability and potential impact of an early intervention and disease prediction technique are significant.

描述（由申请人提供）：当大脑在发育过程中受伤时，不仅会影响大脑的即时功能，还会影响未来学习和获得技能的能力。我们建议建立和模拟多尺度计算模型的影响，早期结构损伤对未来的运动功能的皮质和脊髓。我们将使用可编程芯片（FPGA）和新的数学理论“李克维演算”来构建30万个神经元的模拟，其运行速度比实时快500倍。该模型将拟合两次访问间隔一年的儿童的肌电图和运动学数据，并将通过与一年后的第三次访问进行比较来测试预测。对早期损伤影响的高速模拟有可能彻底改变发育性神经缺陷的治疗，因为它可以在一周内模拟未来10年的变化。通过这样做，它可以预测疾病进展，预测未来的治疗效果，并详细了解脑损伤与运动，感知和行为障碍之间的相互作用。由于这些预测，我们可以更早地进行干预，根据每个患者的疾病情况进行定制治疗。通过早期干预，有可能减轻或阻止疾病的自然进展。超过750，000名美国儿童和成人受到发育性脑障碍，早期获得性脑损伤或儿童进行性脑疾病的影响，早期干预和疾病预测技术的适用性和潜在影响非常重要。
