Extending Power Series Methods For The Hodgkin-Huxley Equations, Including Sensitive Dependence, James S. Sochacki
Extending Power Series Methods For The Hodgkin-Huxley Equations, Including Sensitive Dependence, James S. Sochacki
CODEE Journal
A neural cell or neuron is the basic building block of the brain and transmits information to other neurons. This paper demonstrates the complicated dynamics of the neuron through a numerical study of the Hodgkin-Huxley differential equations that model the ionic mechanisms of the neuron: slight changes in parameter values and inputted electrical impulses can lead to very different (unexpected) results. The methods and ideas developed for the ordinary differential equations are extended to partial differential equations for Hodgkin-Huxley networks of neurons in one, two and three dimensions.
Neuroscience Of Stress & Addiction: A Digitally Animated Video On How These Brain Systems Interact And Influence Each Other From Early Life Stress To Withdrawal, Claire Bacon-Brenes
Neuroscience Of Stress & Addiction: A Digitally Animated Video On How These Brain Systems Interact And Influence Each Other From Early Life Stress To Withdrawal, Claire Bacon-Brenes
Scripps Senior Theses
Alcohol addiction and stress are both highly prevalent health conditions impacting our society. With stress on the rise in college students and alcohol addiction impacting 19.7 million Americans as of 2017, communication around the science of these issues is ever important because of stigma around them. This digitally animated video effectively explains alcohol addiction and stress on a neurobiological level with college science students as the audience, including two important examples of how stress and alcohol addiction interact. Stress experienced early in life is a known risk factor in developing addiction due to dysregulation of the reward pathway and altered …
Biomechanics And Neural Control Of Movement: Cmi's Effects On Downstream Motor Processing And Gait In Forwards And Backwards Walking, Christopher Choi
Biomechanics And Neural Control Of Movement: Cmi's Effects On Downstream Motor Processing And Gait In Forwards And Backwards Walking, Christopher Choi
CMC Senior Theses
Analyzing the effects of cognitive motor interferences (CMI) on walking is usually done in patients with neurological comorbidity or during forward walking (FW). However, there are few studies that examine gait differences between FW and backward walking (BW) under the presence of CMI when speed is kept constant on a treadmill. In this study we examined how CMI would disrupt sensory feedback and affect the descending motor pathway. We hypothesized that subjects that walked backwards and were given a cognitive task would show the greatest differences in gait due to a lack of visual input and the presence of CMI. …
