The Neuropathology Core will continue to play a vital role to the Mount Sinai ADRC. The Neuropathology Core serves to obtain autopsy-derived brain specimens from individuals who have been evaluated and followed longitudinally by the Clinical Core especially residents of the Jewish Home and Hospital for the Aged, a very large academically affiliated nursing home. We strive to obtain the brain specimens with the shortest post-mortem interval and for the entire specimen collection the mean postmortem interval is less than 6 hours. The specimens are dissected and preserved in a manner that maximizes their utility for the needs of both the proposed experiments within the Center as well as other AD and aging-related research projects. This includes snap freezing dissected portions of one half of the brain specimen and fixing the other half is freshly prepared paraformaldehyde. The dissection protocol in place allows for the preparation of selected regions of the brain in such a way that the non-biased sampling techniques of stereology can be applied to quantify lesion and neuron numbers. A detailed neuropathologic workup is carried out to establish a neuropathologic diagnosis as well as to document the extent and distribution of relevant neuropathologic lesions. These data are entered into an extensive data base which can be integrated into the clinical data base for the purpose cliniconeuropathologic correlative investigations. Because this Brain Bank has been operating for approximately 18 years, an efficient and effective operating structure for the Brain Bank already exists. The tissues we have collected have been extensively used in a wide range of studies. They are extensively requested both by researchers within the ADRC, the greater Mount Sinai research community and by many other investigators throughout the US and even internationally. The overall aim of this core is to continue to maintain and operate the Brain Bank in such a way as to meet the needs of the cores and studies in the ADRC in an optimal fashion as well as the research community both at Mount Sinai and elsewhere.

神经病理学核心将继续对西奈山ADRC发挥至关重要的作用。神经病理学核心有助于从经过评估和纵向纵向的人的个人中获得尸检衍生的大脑标本，尤其是在犹太人家庭和医院的居民中，是一个年龄较大的学术界隶属养老院。我们努力以最短的验尸间隔获得大脑样本，对于整个样品收集，平均验尸间隔小于6小时。将标本以最大化其效用的方式进行解剖和保存 项目。这包括快速冻结脑样本的一半的解剖部分，并固定另一半是新鲜准备的甲醛。解剖方案允许制备大脑选定区域的方式，使得可以将无偏见的立体抽样技术应用于量化病变和神经元数量。进行了详细的神经病理检查，以建立神经病理学诊断，并记录相关神经病变病变的程度和分布。这些数据被输入一个广泛的数据库，可以将其集成到临床数据库中，以进行目的，以进行临床研究基础。因为这个大脑银行已经 运营大约18年，已经存在了大脑库的高效工作结构。我们收集的组织已在广泛的研究中广泛使用。 ADRC内部的研究人员，大西奈山研究社区以及美国乃至国际上的许多其他研究人员都广泛要求它们。该核心的总体目的是继续以最佳方式满足ADRC的核心和研究的需求以及在西奈山和其他地方的研究界，以满足ADRC的核心和研究的需求。
