Relationship Between Physiological And Clinical Measures Of Prospective Memory In Individuals With Mild Acquired Brain Injury, Severe Acquired Brain Injury And Healthy Adults, Consuelo M.A Pedro
Relationship Between Physiological And Clinical Measures Of Prospective Memory In Individuals With Mild Acquired Brain Injury, Severe Acquired Brain Injury And Healthy Adults, Consuelo M.A Pedro
Senior Theses and Projects
Prospective memory (PM) involves the ability to form and realize intentions after a time delay (Einstein & McDaniel, 1990). This study examines the relationship between clinical measures of PM and an event-related potential paradigm (West & Ross-Munroe, 2002). Electrophysiological and behavioral data were collected while subjects performed a computerized laboratory PM measure and was compared to a clinical measure, the Memory for Intentions Screening Test (MIST) (Raskin, Buckheit, & Sherrod, 2011) in healthy adults (HA), individuals with severe acquired brain injury (sABI) and mild acquired brain injury (mABI). Individuals with sABI performed significantly worse than individuals with mABI and HA …
Resting-State Functional Network Disruptions In A Rodent Model Of Mesial Temporal Lobe Epilepsy (Tle), Ravnoor Singh Gill
Resting-State Functional Network Disruptions In A Rodent Model Of Mesial Temporal Lobe Epilepsy (Tle), Ravnoor Singh Gill
Electronic Thesis and Dissertation Repository
Mesial temporal lobe epilepsy (TLE) is the most common form of drug-refractory epilepsy. The clinical application of non-invasively mapped networks using resting-state functional magnetic resonance imaging (rsfMRI) in humans has been rather limited due to heterogeneous (varying etiology, drugs, onset, latent period, etc.) patient groups. We employed a pharmacological (kainic acid) rodent model of TLE to measure the extent of functional network disruptions using rsfMRI, and study selected behaviors and olfactory to hippocampus transmission. Graph theoretical network modelling and analysis revealed significant increase in functional connectivity connectivity to the temporal lobe (hippocampus) in epileptic-rats compared to controls in the limbic …
The Effect Of Silver Nanoparticles On Synaptic Responses In The Lateral Giant Escape Circuit Of The Crayfish, Samantha N. Adkins
The Effect Of Silver Nanoparticles On Synaptic Responses In The Lateral Giant Escape Circuit Of The Crayfish, Samantha N. Adkins
Theses, Dissertations and Capstones
The lateral giant neuron in the crayfish is a neuron that controls the reflexive escape response; the context and experience-dependent tuning of this response is critical for survival. Serotonin modulates synaptic responses in this neuron, and social experiences (stress) changes the modulatory role of serotonin. I investigated the mechanisms of induced synaptic response changes and serotonergic modulatory changes after silver nanoparticle exposure to ask if 1) contaminant induced stress changes serotonergic modulation in a manner consistent with social stress and 2) shed light on potential neurotoxic effects of widely used, but poorly understood nanomaterials. Our data show that stress induced …
Cortisol Levels And Voltage Conditions Of College Students, Adriana Steffens
Cortisol Levels And Voltage Conditions Of College Students, Adriana Steffens
Walden Dissertations and Doctoral Studies
There is a limited research base on low voltage brain conditions, which are characterized by electrical activity being measured at below 20 microvolts. The purpose of this study was to examine the relationship between saliva cortisol levels and voltage using an EGG in a college student population. Illuminating this relationship is important to inform how low voltage conditions can affect daily memory and cognitive functioning of undergraduate college students that may be a result of stress. The college student population may be vulnerable to the low voltage condition because of stress from the transition between teenage and adult life and …

Somatostatin (SST) is a neuropeptide hormone that regulates the release of secondary hormones. Evidence suggests SST plays a neuromodulatory role due to its distribution throughout the central nervous system. Interestingly, SST has been suggested to affect the carotid body, the small peripheral chemoreceptors that regulate breathing. It has been shown that the peripheral chemoreflex sensitivity to CO2 and hypoxia is reduced by SST in humans (Pedersen et al., 1999; Pandit et al., 2014). SST has also been found to inhibit whole cell Ca2+ currents recorded from adult rat carotid body type I cells (e Silva & Lewis, 1995), but the …
