This Core is not based on an existing Core and represents a novel concept that is likely to increase the research capabilities of a large number of Neuroscience Investigators as well as promote collaborations. The goal of this Core is to provide equipment for electrophysiological experiments as well as the technical capability for performing the experiments. This will allow Neuroscience investigators to carry out preliminary experiments that will test the feasibility of applying electrophysiological approaches to ongoing projects. In addition, the Core will provide a well-defined venue for Neuroscience Investigators to obtain expert advice regarding establishing electrophysiological methods in their own laboratories. This Core will be situated adjacent to the laboratories of the Director and Co-Directors (Dunlap; Blaustein & Cox). A key component of the Core that will be critical for its success is the hiring of an expert electrophysiologist. The equipment available will allow a variety of recording techniques including whole cell current and voltage clamp, single channel recording, two electrode voltage clamp, tissue slice single cell current and voltage clamp and extracellular field recording. As currently proposed, the Core would eventually have 2 rigs, the 2nd one being purchased in the 2nd year and dedicated primarily for slice electrophysiology. While the idea of having an electrophysiology core is well regarded, it is important to have realistic goals for the core. The nuances associated with slice recording that are unique to each preparation raise questions about the feasibility of incorporating slice electrophysiology into the Core. The goals of the 1st rig seem more realistic and feasible to achieve with the hiring of a well trained electrophysiologist.

该核心并非基于现有核心，而是代表了一个新颖的概念，可能会提高大量神经科学研究人员的研究能力并促进合作。该核心的目标是提供电生理实验的设备以及进行实验的技术能力。这将使神经科学研究人员能够进行初步实验，测试将电生理学方法应用于正在进行的项目的可行性。此外，核心将为神经科学研究人员提供一个明确的场所，以获得有关在自己的实验室建立电生理学方法的专家建议。该核心将位于毗邻 主任和联合主任（Dunlap；Blaustein & Cox）的实验室。核心的一个关键组成部分对其成功至关重要，那就是聘请一位专业的电生理学家。可用的设备将允许多种记录技术，包括全细胞电流和电压钳、单通道记录、两电极电压钳、组织切片单细胞电流和电压钳以及细胞外场记录。按照目前的提议，Core 最终将拥有 2 台设备，第二台设备将在第二年购买，主要用于切片电生理学。虽然拥有电生理学核心的想法得到了广泛认可，但为核心制定现实的目标也很重要。相关的细微差别 每种制剂独特的切片记录提出了将切片电生理学纳入核心的可行性的问题。通过聘请训练有素的电生理学家，第一个装备的目标似乎更现实、更可行。
