The goal of this project is to be able to streamline a protocol for conducting ERGs on zebrafish from mice ERG protocol already present in Dr. Renna’s lab. The objective is to create a protocol specifically for zebrafish and to eliminate any issues that occur when transiting from a mice ERG protocol to a zebrafish ERG protocol and to obtain a light response from zebrafish retinae in differing light intensities. Dr. Renna’s lab has designed an Ex Vivo ERG system with less electrical interference creating defined electrical responses from mouse retina. The setup allows for continual perfusion of the retinal …

Community-Derived Core Concepts For Neuroscience Higher Education, Audrey Chen, Kimberley A. Phillips, Jennifer E. Schaefer, Patrick M. Sonner
Biology Faculty Publications
Core concepts provide a framework for organizing facts and understanding in neuroscience higher education curricula. Core concepts are overarching principles that identify patterns in neuroscience processes and phenomena and can be used as a foundational scaffold for neuroscience knowledge. The need for community-derived core concepts is pressing, because both the pace of research and number of neuroscience programs are rapidly expanding. While general biology and many subdisciplines within biology have identified core concepts, neuroscience has yet to establish a community-derived set of core concepts for neuroscience higher education. We used an empirical approach involving more than 100 neuroscience educators to …

The Role Of Complement In Stroke And Traumatic Brain Injury, Christine Couch
MUSC Theses and Dissertations
Brain and neural injury are a non-specific disease category that includes traumatic brain injury (TBI) and stroke. Both TBI and stroke are common, costly, and leading causes of severe disability in adults. Both stroke and TBI are responsible for substantial disability in working age adults, with stroke being the second leading cause of death worldwide [1] and TBI a major cause of disability in people younger than their 40's [2]. The immune response after brain injury is multifactorial and involves both local and systemic events at the cellular and molecular level. The complement system is a component of both the …

Examining The Use Of Expressive Arts Therapies In Neurorehabilitation Treatment Planning, Rebecca J. Horner
Expressive Therapies Capstone Theses
Those undergoing neurorehabilitation after stroke and traumatic brain injury report a diminished sense of overall wellness. This paper examines the conceivable benefits of introducing expressive arts therapies, which is the therapeutic use and combination of the visual arts, movement, drama, music, writing and other intermodal creative processes, into physical therapy and neurorehabilitation treatment planning. Expressive arts therapies have the capacity to engage with an individual’s physical, emotional, social and spiritual states concurrently. They simultaneously offer the ability to promote an increased sense of well-being, address mind-body disconnects, and process trauma non-verbally.
The sections of this narrative literature review focus on …
Disentangling Sentience From Developmental Plasticity,

Disentangling Sentience From Developmental Plasticity, Jonathan Birch
Animal Sentience
Plants, like animals, display remarkable developmental plasticity, inviting the metaphorical use of terms like “decision” and “choice”. In the animal case, this is not taken to be evidence of sentience, because sentience is a complex product of development, not something that guides it. We should apply the same standards when evaluating the evidence in plants. It is hard to overstate the contrast with the case of invertebrates such as octopuses, where pain markers that were originally developed for use in mammals have been clearly demonstrated and plausible neural substrates for sentience have been identified.

Demystifying The Mind-Body Connection: The Neuroscience Behind How Thoughts Impact Physical Health, Sofia Pantis
Undergraduate Honors Theses
The beliefs, emotions, and experiences that constitute a mindset shape numerous aspects of one’s reality, but in particular, health. Health is defined by not only the physical state of one’s body, but also the content of one’s mind. The integration of the mind and body is often associated with naturopathic medicines or pseudoscience, and thus is usually left out of Western medicinal practices. This review aims to demystify the mind-body connection in health and wellness by introducing it within an empirical, neuroscientific landscape. This research supports the hypothesis that mind over matter rings true even at the biochemical level. Activation …

There is now compelling evidence that the spatiotemporal remapping carried out by fixational eye movements (FEMs) is an essential step in visual processing. Moreover, the overall Brownian-like statistics of FEMs are calibrated to map fine spatial detail into the temporal frequency range to which retinal circuitry is tuned. Here, we tested the hypothesis that the detailed spatial characteristics of FEMs can be adjusted to task demands via cognitive influences that operate even in the absence of a visual stimulus. We examined FEMs in a task that required subjects (N=6) to report which of two letters was displayed. Trials were blocked; …

Automated Delineation Of Visual Area Boundaries And Eccentricities By A Cnn Using Functional, Anatomical, And Diffusion-Weighted Mri Data, Noah C. Benson, Bogeng Song, Toshikazu Miyata, Hiromasa Takemura, Jonathan Winawer
MODVIS Workshop
Delineating visual field maps and iso-eccentricities from fMRI data is an important but time-consuming task for many neuroimaging studies on the human visual cortex because the traditional methods of doing so using retinotopic mapping experiments require substantial expertise as well as scanner, computer, and human time. Automated methods based on gray-matter anatomy or a combination of anatomy and functional mapping can reduce these requirements but are less accurate than experts. Convolutional Neural Networks (CNNs) are powerful tools for automated medical image segmentation. We hypothesize that CNNs can define visual area boundaries with high accuracy. We trained U-Net CNNs with ResNet18 …

Understanding circuit properties from physiological data presents two challenges: (i) recordings do not reveal connectivity, and (ii) stimuli only exercise circuits to a limited extent. We address these challenges for the mouse visual system with a novel neural manifold obtained using unsupervised algorithms. Each point in our manifold is a neuron; nearby neurons respond similarly in time to similar parts of a stimulus ensemble. This ensemble includes drifting gratings and flows, i.e., patterns resembling what a mouse would “see” running through fields.
Regarding (i), our manifold differs from the standard practice in computational neuroscience: embedding trials in neural coordinates. Topology …

Constraining The Binding Problem Using Maps, Zhixian Han, Anne Sereno
MODVIS Workshop
We constrained the binding problem by creating maps of different attributes. We compared the performance of different models with different maps in our current study. Our preliminary results showed that the performance of the model is the highest when location maps were used. These results suggest that the optimal way to constrain the binding problem is to create location maps of different attributes.

From Image Gradients To A Perceptual Metric Space, Alan Johnston
MODVIS Workshop
How do we achieve a sense of spatial dimension from a sense of location? There are three predominant ideas about how we achieve this; spatial isomorphism, in which what we see reflects differences in distance or size in the brain; that spatial extent depends upon motor sensations or intentions related to eye movements; and that distance is computed from the degree of correlation in neural activity between adjacent locations, with distance inversely proportional to the correlation. There are problems with each of these approaches, for example, neural correlation may depend more on image structure than adjacency - consider the case …

A Dynamical Model Of Binding In Visual Cortex During Incremental Grouping And Search, Daniel Schmid, Daniel A. Braun, Heiko Neumann
MODVIS Workshop
Binding of visual information is crucial for several perceptual tasks. To incrementally group an object, elements in a space-feature neighborhood need to be bound together starting from an attended location (Roelfsema, TICS, 2005). To perform visual search, candidate locations and cued features must be evaluated conjunctively to retrieve a target (Treisman&Gormican, Psychol Rev, 1988). Despite different requirements on binding, both tasks are solved by the same neural substrate. In a model of perceptual decision-making, we give a mechanistic explanation for how this can be achieved. The architecture consists of a visual cortex module and a higher-order thalamic module. While the …

MODVIS Workshop
Efficient coding provides a concise account of key early visual properties, but can it explain higher-level visual function such as shape perception? If curvature is a key primitive of local shape representation, efficient shape coding predicts that sensitivity of visual neurons should be determined by naturally-occurring curvature statistics, which follow a scale-invariant power-law distribution. To assess visual sensitivity to these power-law statistics, we developed a novel family of synthetic maximum-entropy shape stimuli that progressively match the local curvature statistics of natural shapes, but lack global structure. We find that humans can reliably identify natural shapes based on 4th and …

Optical Perturbation Of Protein Kinase A Activity Via Photoactivatable Inhibitor Peptides, Peter Chen
McKelvey School of Engineering Theses & Dissertations
Protein Kinase A (PKA) plays important roles in diverse biological processes such as sleep, long term memory, and synaptic plasticity. In addition, PKA also acts as an integrator of neuromodulator signaling though G protein-coupled receptor activation. However, despite genetic knockout and pharmacological inhibition experiments that demonstrate the importance of PKA, it is unclear where, when, or how PKA plays these roles in cellular physiology and behavior. In order to better understand the function of PKA in these processes, and how neuromodulator signaling drives complex behavioral changes, there exists a need for a method to selectively activate/inactivate PKA with high spatial …
