Empathy-Based Conservation: An Interdisciplinary Approach To Conservation Policy And Decision-Making, Kaitlyn Delashmutt

Department of Environmental Studies: Undergraduate Student Theses

In the late 20^th century, neuroscientists in Italy discovered a neuron in the brain capable of mentally mimicking the emotions derived from the actions of others (Rizzolatti and Craighero, 2004). It is the process that makes your elbow ache when someone else knocks their elbow on the counter or the uncontrollable smile that creeps up when someone smiles at you. No questions asked, people intuitively sense what others are feeling. The old school of thought was that humans deduced through logic and reason the actions of others and interpreted the emotions through a rational process (Carew et al, 2008). …

Six Types Of Multistability In A Neuronal Model Based On Slow Calcium Current, Tatiana Malashchenko, Andrey Shilnikov, Gennady Cymbalyuk

Neuroscience Institute Faculty Publications

Background: Multistability of oscillatory and silent regimes is a ubiquitous phenomenon exhibited by excitable systems such as neurons and cardiac cells. Multistability can play functional roles in short-term memory and maintaining posture. It seems to pose an evolutionary advantage for neurons which are part of multifunctional Central Pattern Generators to possess multistability. The mechanisms supporting multistability of bursting regimes are not well understood or classified.

Methodology/Principal Findings: Our study is focused on determining the bio-physical mechanisms underlying different types of co-existence of the oscillatory and silent regimes observed in a neuronal model. We develop a low-dimensional model typifying the dynamics …

Mind Perception: Real But Not Artificial Faces Sustain Neural Activity Beyond The N170/Vpp, Thalia Wheatley, Anna Weinberg, Christine Looser, Tim Moran, Greg Hajcak

Dartmouth Scholarship

Faces are visual objects that hold special significance as the icons of other minds. Previous researchers using event-related potentials (ERPs) have found that faces are uniquely associated with an increased N170/vertex positive potential (VPP) and a more sustained frontal positivity. Here, we examined the processing of faces as objects vs. faces as cues to minds by contrasting images of faces possessing minds (human faces), faces lacking minds (doll faces), and non-face objects (i.e., clocks). Although both doll and human faces were associated with an increased N170/VPP from 175–200 ms following stimulus onset, only human faces were associated with a sustained …

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

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.

Memory And Punishment, O. Carter Snead

Journal Articles

This article is the first scholarly exploration of the implications of neurobiological memory modification for criminal law. Its point of entry is the fertile context of criminal punishment, in which memory plays a crucial role. Specifically, this article will argue that there is a deep relationship between memory and the foundational principles justifying how punishment should be distributed, including retributive justice, deterrence, incapacitation, rehabilitation, moral education, and restorative justice. For all such theoretical justifications, the questions of who and how much to punish are inextricably intertwined with how a crime is remembered - by the offender, by the sentencing authority, …

Neural Responses To Vibration During Wobble Board Balancing, Michael Nguyentat

CMC Senior Theses

Falling, an epidemic most prevalently seen in the elderly population, accounts for the majority of injury-related cases seen by emergency departments across the United States. Unfortunately, with no large-scale institutionalization of a solution, the problem is only expected to exacerbate as our planet’s population approaches the 7 billion mark. In the wake of the recent surge of falls among the elderly, Japan has implemented a program to include unicycling in the physical education curriculum for elementary schools across the country. The goal for this program is to encourage children to establish strong fundamental balancing skills, which could potentially alleviate the …

Minimal Information For Neural Electromagnetic Ontologies (Minemo): A Standards-Compliant Method For Analysis And Integration Of Event-Related Potentials (Erp) Data, Gwen Frishkoff, Jason Sydes, Kurt Mueller, Tim Curran, John F. Connolly, Kerry Kilborn, Dennis L. Molfese, Charles Perfetti, Allen D. Malony

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

We present MINEMO (Minimal Information for Neural ElectroMagnetic Ontologies), a checklist for the description of event-related potentials (ERP) studies. MINEMO extends MINI (Minimal Information for Neuroscience Investigations)to the ERP domain. Checklist terms are explicated in NEMO, a formal ontology that is designed to support ERP data sharing and integration. MINEMO is also linked to an ERP database and web application (the NEMO portal). Users upload their data and enter MINEMO information through the portal. The database then stores these entries in RDF (Resource Description Framework), along with summary metrics, i.e., spatial and temporal metadata. Together these spatial, temporal, and functional …
