This report describes a unique undergraduate research and teaching collaboration between investigators at two institutions, one a relatively small, primarily undergraduate institution and the other a large, urban research-intensive university. The program incorporates three major facets. First, undergraduates participate in a weekly collaborative lab meeting involving instructors from both institutions and held via remote video. Student-led discussions and presentations dominate these meetings, and the unique format promotes novel interactions between students and instructors. Second, students carry out investigative studies centered on understanding the role extracellular pH dynamics play in regulating neuronal processing. Students carry out studies on isolated neurons and glia throughout the fall and spring semesters, and primarily use a noninvasive electrophysiological technique, termed self-referencing, for extracellular pH measurements. The technique is relatively simple and readily learned and employed by undergraduates, while still being powerful enough to provide novel and meaningful research results. The research component is expanded for several students each summer who are selected to participate in summer research with both PIs and graduate students at the major research institution. Finally results gathered during the year and over the summer are disseminated at institutional symposia, undergraduate neuroscience symposia, national society meetings, and in submitted journal manuscripts. Preliminary observations and findings over three years support the aim of this research experience; to create a productive environment that facilitates deep-level understanding of neurophysiological concepts at the undergraduate level and promotes intellectual development while cultivating an excitement for scientific inquiry in the present and future.
本报告描述了两个机构的研究人员之间独特的本科研究与教学合作,其中一个是规模相对较小、主要专注于本科教育的机构,另一个是大型的、位于城市的研究密集型大学。该项目包含三个主要方面。首先,本科生参加每周一次的合作实验室会议,会议由来自两个机构的教师通过远程视频主持。学生主导的讨论和展示在这些会议中占主导地位,这种独特的形式促进了学生与教师之间新颖的互动。其次,学生开展调查研究,重点是了解细胞外pH动态在调节神经元处理过程中所起的作用。学生在整个秋季和春季学期对分离的神经元和神经胶质细胞进行研究,主要使用一种称为自参考的非侵入性电生理技术来测量细胞外pH值。该技术相对简单且本科生容易学习和应用,同时仍强大到足以提供新颖且有意义的研究结果。每年夏天,会挑选几名学生参与主要研究机构的PI和研究生的暑期研究,从而扩展研究部分。最后将全年及夏季收集到的结果在机构研讨会、本科神经科学研讨会、全国性学会会议以及提交发表的期刊稿件中进行传播。三年来的初步观察和发现支持了这项研究经历的目标;创造一个富有成效的环境,促进本科层面深入理解神经生理学概念,促进智力发展,同时培养对当前和未来科学探究的热情。
