Core A is an essential component of this Program Project, as it serves the research needs of four of the five Projects proposed by the Principal and Co-Investigators. The major research instrument in the Core is a JEOL 100 CX II electron microscope, originally purchased by funds primarily provided by this Program Project in 1986. The electron microscope permits analysis of neurons and their synaptic connections. Many of the studies proposed in this application deal with changes in neural networks that are believed to underlie pain syndromes, and the work could not be carried out without the instrument. The funds requested in the Core A budget support part of the salary of a senior electron microscopy technician, who oversees the unit, trains new users of the microscope, and keeps it in optimal running order. Funds are also requested to pay 50% of the annual cost of a service contract. An additional instrument, a BioRad Scanning Confocal microscope, is housed in the Keck Foundation Center for Integrative Neuroscience; three of the Co-Investigators are members of the Center. The confocal microscope is used to examine populations of neurons stained by immunofluorescence to identify various synaptic transmitters and receptors. Several of the research projects in this proposal make use of this instrument as a research tool. Fifty percent of the annual cost of a service contract of the confocal microscope is requested in this proposal.

核心A是本计划项目的一个重要组成部分，因为它满足了首席和联合调查员提出的五个项目中的四个项目的研究需要。核心的主要研究仪器是JEOL 100 CX II电子显微镜，最初是由1986年该计划项目提供的资金购买的。电子显微镜可以分析神经元及其突触连接。这项申请中提出的许多研究涉及神经网络的变化，这些变化被认为是疼痛综合征的基础，如果没有仪器，这项工作就无法进行。核心A预算中要求的资金支持一名高级电子显微镜技术员的部分工资，该技术员负责监督该单位，培训显微镜的新用户，并使其处于最佳运行状态。基金还被要求支付服务合同年度成本的50%。另一台仪器，一台BioRad扫描共聚焦显微镜，被安置在凯克基金会综合神经科学中心；三名联合调查人员是该中心的成员。共聚焦显微镜被用来检查免疫荧光染色的神经元群体，以识别各种突触递质和受体。这项建议中的几个研究项目利用这一工具作为研究工具。本提案要求支付共焦显微镜服务合同年费用的50%。
