Network synchronization across the longitudinal axis of the developing rat hippocampus
No full textEpilepsy is a neurological disorder characterized by recurrent seizures. Researching epilepsy
requires animal models, as the brain manipulation required to understand epileptogenic activity
is not possible in humans. Extracellular recordings measure network level activation in slice
models of epilepsy. A magnesium-free solution is often used in slice physiology to increase
excitation, through enhanced glutamate receptor activity. Magnesium blocks the activation of
glutamate receptors via binding near the pore region. Magnesium also lowers calcium’s ability to
initiate presynaptic neurotransmitter release. We aim to elucidate the mechanisms of a dorsal neuro-protective system, which reduces the excitability of dorsal hippocampal tissue with age.
While the mechanisms underlying the magnesium-free model are well established, the effects of
this model across the longitudinal axis of the hippocampus and throughout development have not
been clearly characterized. We studied the effects of the magnesium-free model through
extracellular field recordings of CA1 pyramidal neurons from dorsal and ventral hippocampal
slices throughout development, and found young, dorsal hippocampal tissue to be the most
excitable. Additionally, our data suggests the effect of no magnesium is minimal in ventral
slices. These data support the theory of the dorsal protection system being critical in the
reduction of excitability seen with age
"Liberation" Official Installation Image
No full textThis digital image was photographed by Chip Pankey and uploaded to DLynx by the Visual Resources Center in April, 2018.This is an image from the "Liberation" exhibition, presented by The Collective. The Collective is a Memphis- based nonprofit organization that was launched in 2015. Their mission is to inspire and cultivate creativity within their community, to provide a platform for African American artists in Memphis to display their talents, and use that creative expression as a vehicle to uplift their community. The 'Liberation" exhibition was held from February 23- March 24. A panel discussion with the artists took place on March 13 , and a closing reception and performance took place in the gallery on March 23

Spring Beginning Painting Project 1: Environment
No full textThis painting was digitized and uploaded to DLynx by the Visual Resources Center in Spring 2018.This is a painting created by Madison Peticolas. It was submitted as part of the first project assigned to the Beginning Painting class of Spring 2018 taught by Carl Moore. This assignment, titled "Environment," required students to complete 20 paintings on a 9 x 12 inch cold press illustration board and two color charts. The "Environment" subject could reference objects from everyday life or a still life that was set up in the studio

what are we?
No full textArtwork photographed and uploaded to DLynx by Rosie Meindl in May 2019. The college purchased this artwork in December 2018.This self portrait was painted by Sarah Hatfield in 2018. The artist's statement about this piece reads: "Requiring adoration to foster confidence and security keeps me from ever truly knowing myself. I find affirmation in intimate moments, opening up to people in a physical way that I cannot express through words. My dependency on people I love becomes apparent when I can no longer see them as a separate entity. Layers of paint accumulate as I try to discern between what I know of myself and the people that I am dependent on. When one person fails me I adopt others into my support system, using the infatuation of one to compensate for the shortcomings of another. The physicality of painting mirrors the way that I try to express myself to partners. These convoluted paintings begin as identifiably figurative pieces that grow as I attempt to better understand how people relate to one another. I use paint to explore the tension and boundaries in relationships. Gradually, as the paint builds, resolute bodies begin to dissolve into more abstract notions toward bodily references and the distinction between individuals becomes less clear. An emphasis is placed on the spaces of connection. The way paint meets on canvas explores the interactions that we experience. Brushstrokes often mimic a dull panic we may feel when confronted with separation or loss. Whereas, linear marks reference distorted and unrecoverable figures that emerge as we struggle to confront the confusing and uncertain terrain of dependency. Colors blend as the paint works to construct a moment of representational self-portraiture within this study of vulnerability.
