Summary Neuroscience has an essential requirement for large-scale perturbation tools. Such tools would be transformative in the mapping of brain function and the diagnosis and treatment of neurological disorders. The proposed project is aimed at uncovering a potential therapeutic role for US neuromodulation (USNM) in Alzheimer’s disease, following up on early phenomenological observations that focused US may have such an impact. Our project’s goal is to use state-of-the-art in vivo imaging techniques to understand how US could be used to study and manipulate cerebrospinal fluid (CSF) flow in the brain, with applications focused on Alzheimer’s disease, using combined US and simultaneous fluorescence microscopy of amyloid-β and tau. We will study if USNM effects in the brain can lead to changes in blood and CSF flow, and whether USNM induced flow effect amyloid-β or tau clearance in the brain.

概括 神经科学对大规模扰动工具有基本要求。 将对大脑功能的绘制以及疾病的诊断和治疗产生革命性的影响 拟议的项目旨在揭示潜在的治疗作用。 阿尔茨海默病的美国神经调节（USNM），跟进早期现象学 聚焦美国的观察可能会产生这样的影响。 我们项目的目标是使用最先进的体内成像技术来了解如何 US 可用于研究和操纵大脑中的脑脊液 (CSF) 流动， 专注于阿尔茨海默氏病的应用，结合使用超声和同步荧光 β 淀粉样蛋白和 tau 蛋白的显微镜检查 我们将研究 USNM 对大脑的影响是否会导致变化。 血液和脑脊液流量中的变化，以及 USNM 诱导的流量是否会影响淀粉样蛋白-β 或 tau 蛋白的清除 脑。
