Characterizing and Investigating the Electrophysiological Properties of the Plastic Cricket Auditory System in Response to Cooling
Date: 2022-01-01
Creator: Hannah Tess Scotch
Access: Open access
- The auditory system of the Mediterranean field cricket (Gryllus bimaculatus) is capable of profound compensatory plasticity. Following deafferentation due to the loss of an auditory organ, the dendrites of intermediate auditory neuron Ascending Neuron 2 (AN-2) grow across the midline and functionally connect to contralateral afferents. The loss of the auditory organ can be mimicked with reversible cold-deactivation, in which cooled Peltier elements silence the auditory organ and its afferents. Though this would presumably prevent AN-2 from firing, cooling instead induces a novel firing pattern called DOPE (delayed-onset, prolonged-excitation). In this study, intracellular physiological recordings were completed before, during, and after cooling in response to “chirp” and “pulse” sounds. Analysis was performed within and across crickets to characterize DOPE. Results revealed expected variability across individuals, as well as a wider spread of onset delay and a decrease in spike frequency and number of spikes per burst relative to baseline within individuals during cooling. Generally, subsequent warming only partially restored the neuronal responses to baseline as measured by all three parameters. This was particularly true in response to “pulse” stimuli. Future experiments will investigate if DOPE is caused by synaptic inputs or intrinsic properties of AN-2, as well as the role of inhibition in the circuit. Eventually, we hope to develop a complete model of the auditory circuit for future investigations of plasticity, with ramifications for treating human neuronal injury.

Echoing Memories and Synchronicities of an Adoptive Family: A Memoir
Date: 2022-01-01
Creator: Gemma Jyothika Kelton
Access: Open access
- Published narratives about adoptions have typically been told from the perspective of the adopter. In recent years, Asian American writers who are part of the transracial, transcultural, and even transcultural adoptions, have published their narratives and expanded the discourse on adoptions to include the voices of orphans and adoptees. While there are still not many published works by adoptees, more and more writers are coming forward with their own stories separate from their adoptive parents. This honors project is a memoir and a work of nonfiction that examines the author’s experiences as an adoptee from India. It explores the issues of skin color bias (or colorism) in Indian adoption, as well as Indian government policies on inter-country and in-country adoptions. This memoir also delves into the complexities of an adoptive mother-daughter relationship, particularly in the transracial context. The work of non-fiction tells the story of a single white American mother adopting a 10 year old Indian girl to the United States. Written from the adoptee’s perspective, the memoir follows the different points of transitions in both the mother’s and the daughter’s lives and the ensuing challenges, chaos, vulnerabilities, and moments of tenderness, mutual support, care, and love that blooms in their adoptive mother-daughter relationship. This work draws upon narratives of Asian American women writers including Michelle Zauner’s Crying in H-Mart, Nicole Chung’s All You Can Ever Know, and Nishta J. Mehra’s Brown White Black to acknowledge their own voices and give credibility to the adoptee narrative.
