Illustrating Neuroaesthetics, Madeleine Golitz
Illustrating Neuroaesthetics, Madeleine Golitz
Summer Research
This body of art attempts to bridge two subjects, visual art and neuroscience. It does so by illustrating five topics in neuroaesthetics, the study of how we see and perceive art. I believe beautiful things can happen at the intersections of interdisciplinary subjects and wanted to explore this one further.
The first piece begins with a straightforward introduction to the structure of the human eye. The drawings following increase in complexity, working further up the visual process. For instance, the second depicts intermediate pathways in the brain using Op art techniques. The third illustrates how memory influences how we see …
Timing Is Everything: Temporal Dynamics Of Brain Activity Using The Human Connectome Project, Francesca Lofaro
Timing Is Everything: Temporal Dynamics Of Brain Activity Using The Human Connectome Project, Francesca Lofaro
Summer Research
Most neuroimaging studies produce snapshots of brain activity. The goal of this project is to examine the temporal dynamics of how these areas interact through time, using fear as a case study to assess how regions involved in fear interact. Working with Matlab computer code, I sort through the large fMRI dataset known as the Human Connectome Project to extract neuroimaging data from patients with different NIH Toolbox Fear-Somatic survey scores to assess the temporal dynamics between brain regions. The results will allow an understanding beyond which areas are involved, and instead will provide a picture of how these areas …
Metaphors And Mind: An Erp Study Of How The Brain Processes Metaphors, Crystal Poole
Metaphors And Mind: An Erp Study Of How The Brain Processes Metaphors, Crystal Poole
Summer Research
Even though metaphors are frequently used in everyday language, how metaphors are created and comprehended in the brain is not well understood. Metaphors can differ in whether they are conventional (such as “love is war”) or novel (such as “love is a tidal wave”), and an unresolved question is if, and how, novel metaphors might become conventional as they are used. In order to test this question, we will ask participants to respond to literal phrases, conventional metaphors, novel metaphors created by the experimenters, and novel metaphors created by the participants themselves while measuring their brain …
A Sociocognitive Perspective Of The Uncanny Valley, Andre Zamani
A Sociocognitive Perspective Of The Uncanny Valley, Andre Zamani
Summer Research
The “uncanny valley” is the effect of being ‘creeped out’ by things that are very close, but not quite, human (e.g., a ventriloquist dummy). Over the past two summers, I found that intranasal administrations of oxytocin, a hormone which affects attention to external social information, decreased participants’ reaction times when assessing uncanny valley stimuli, but did not affect their ratings of eeriness. Furthermore, oxytocin affected participants’ reaction times the most for stimuli rated to be intermediately eerie but altered their visual attention the most during the perception of stimuli rated to be either not eerie or very eerie. From these …
Entraining Brain Oscillations To Influence Facial Perception, Rosie Irwin
Entraining Brain Oscillations To Influence Facial Perception, Rosie Irwin
Summer Research
Relatively little is known about the role of brain oscillations in relation to cognitive function. While oscillations of all frequencies have be associated with most any neural process, no conclusive data has been found to support if oscillations are simply emergent or if they play a causal role in cognitive functions. To make headway on this problem, we employed entrainment, a technique used to synchronize brain oscillations. Entrainment was achieved by presenting subjects with alternating images of a neutral face and a scrambled face at 4 Hz such that the faces were presented at 2 Hz. After a few seconds …
Effect Of Out-Group Exposure On The Mirror Neuron System, Mackenzie Hepker
Effect Of Out-Group Exposure On The Mirror Neuron System, Mackenzie Hepker
Summer Research
Mirror neurons appear to play an important role in the experience of empathy, and may be critical for understanding the social signals of others in an interactive context between distinctly identified groups. Research has shown that mirror neuron activation is greater when observing in-group members (others that one most identifies with based on a certain factor or number of factors) as opposed to out-group members, which may implicate the mirror neuron system (MNS) in the neural aspect of social bias. However, no research had been conducted on the effect on the MNS of practice in interpreting and internalizing social signals …
Relative Dependence Of Neural Plasticity On Age And Activity In The Bumblebee (Bombus Huntii), Geoffrey Nielsen
Relative Dependence Of Neural Plasticity On Age And Activity In The Bumblebee (Bombus Huntii), Geoffrey Nielsen
Summer Research
Neural Plasticity is one of the most fascinating and complex aspects of neuroscience. Due to the complexity of neural plasticity mechanisms, simple models are used to study neural plasticity. The bumblebee, Bombus huntii provides an ideal model organism with which to study neural plasticity, particularly the way it is affected by age and activity1. The Mushroom Body is the portion of the B. huntii brain that is responsible for higher order sensory integration and experience related learning so it will be the focus of this study.
Visualizing The Correlation Between Human Brain Structure And Function, Douglas Hamilton
Visualizing The Correlation Between Human Brain Structure And Function, Douglas Hamilton
Summer Research
In order to help neuroscience researchers better investigate correlations between human brain structure and function, three visualization techniques were implemented in an existing neuroscience investigation software tool. These techniques aimed to produce effective visualizations of gray matter and white matter in the same virtual scene. The three techniques were: 1) wireframe rendering of the gray matter 2) multiple views of separate data sets with linked vantage point and 3) abstraction of white matter pathways drawn as arcs going outside the gray matter.
