Arts & Sciences Electronic Theses and Dissertations
The hippocampus is a critical brain structure for learning and memory. Neuronal inhibition within the hippocampus, performed by a wide variety of inhibitory interneuron subtypes, is required to organize and regulate the cell activity and circuit operations which underly memory formation. Despite the importance of inhibitory interneurons to the function of the hippocampus, detailed descriptions of the role of interneurons in the regulation of network activity have been limited by difficulties associated with identifying and recording from these cells using traditional electrophysiology techniques, especially in awake, behaving animals. To better investigate the function of hippocampal interneurons in awake, behaving animals, …

Cornichon homolog-3 (CNIH3) is an AMPA receptor (AMPAR) auxiliary protein highly expressed in the dorsal hippocampus (dHPC), a region where AMPARs are critical for spatial memory and synaptic plasticity. A 2016 genome-wide association study (GWAS) by Nelson et al. identified single nucleotide polymorphisms (SNPs) in the gene CNIH3 to be associated with reduced individual risk for the development of opioid use disorder (OUD) in individuals with prior opioid exposure. We previously demonstrated a key role for AMPARs in the dHPC in opioid-associated learning and memory, therefore we hypothesized that CNIH3 in the dHPC may mediate learning and memory processes through …
