Long-Term Neural Activity Recorders Using Energy-Based Sensing, Compressive Computation And Data Logging, Darshit Mehta Aug 2021

Long-Term Neural Activity Recorders Using Energy-Based Sensing, Compressive Computation And Data Logging, Darshit Mehta

McKelvey School of Engineering Theses & Dissertations

Insects are ideal candidates for developing bio-robotic systems owing to their ability to thrive in almost any environment. For example, neurons in their exquisite olfactory sensory systems can be tapped to create a sensing platform for standoff chemical monitoring. However, for enabling such cyborg systems, it is vital that the neural activity of a freely behaving organism can be measured for long periods of time. The current state-of-the-art neural recording techniques are power-intensive and they either need batteries, which make them too bulky for insects, or they have to maintain a continuous telemetry link to an external power source which …


Sex Differences In The Role Of Cornichon Homolog-3 On Spatial Memory And Synaptic Plasticity, Hannah Elizabeth Frye May 2021

Sex Differences In The Role Of Cornichon Homolog-3 On Spatial Memory And Synaptic Plasticity, Hannah Elizabeth Frye

Arts & Sciences Electronic Theses and Dissertations

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 …


Dedicated Interneuronal Microcircuits Regulated By Behavioral State, Moises William Arriaga May 2021

Dedicated Interneuronal Microcircuits Regulated By Behavioral State, Moises William Arriaga

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, …
