EXPLORING THE EFFECTS OF OFFLINE PARADIGMS AND FEATURE EXTRACTION TECHNIQUES ON PERFORMANCE OF MOTOR IMAGERY BASED BRAIN-COMPUTER INTERFACE
Dick, Joelle F (East Carolina University, 2021-07-15)Motor Imagery (MI) Brain-Computer Interface (BCI) has become a popular way of allowing disabled and healthy individuals to use brain signals to communicate with their environment. However, despite its potential, MI-based ... -
Functional Connectivity Analysis of Visually Evoked ERPs for Mild Cognitive Impairment
Wang, Lana (East Carolina University, 2022-04-28)Mild cognitive impairment (MCI) is considered as the early stage of Alzheimer's disease, characterized as mild memory loss. Using electroencephalogram (EEG) data, a novel method of functional connectivity (FC) analysis can ... -
Healthy Aging Effects on Semantic Processing of Faces and Objects
White, Austin T (East Carolina University, 2019-05-01)Neurodegenerative disorders such as Alzheimer's disease (AD) and mild cognitive impairment (MCI) remain significant health and economic burdens, affecting millions worldwide. Creating affordable and accurate early diagnostic ... -
IMPROVING THE SPEED AND ACCURACY OF THE P300 AUTOMATIC SPELLING SYSTEM THROUGH FACIAL RECOGNITION
Albanese, Thomas J., II (East Carolina University, 2022-07-21)Locked-in syndrome is a condition where an individual does not have control of their muscles, including facial muscles and vocal cords which control speech. Instead of oral speech, sign language, or writing, other methods ... -
Investigating the Performance of the Visual Oddball Paradigm in the Context of Facial Recognition
Abdelfattah, Basel A (East Carolina University, 2021-06-03)The sequential visual oddball paradigm is a technique that is often used to elicit various components of cognitive event related potentials (ERPs). These components may serve as reliable biomarkers for neurodegenerative ... -
LOW RESOLUTION ELECTROMAGNETIC TOMOGRAPHY (LORETA) ANALYSIS OF THE BRAINS ELECTROPHYSIOLOGICAL RESPONSE TO EMOTIONAL VISUAL STIMULI UNDER DIFFERING CONDITIONS
Cadmus, Matthew S (East Carolina University, 2016-07-21)Current methods of diagnosing and monitoring stress include: observing changes in the severity of existing symptoms, the development of new symptoms, hormone level tests, and stress self-assessment surveys. Self-assessment ... -
A novel particle filtering method for estimation of pulse pressure variation during spontaneous breathing
Kim, Sunghan, 1975-; Noor, Fouzia; Aboy, Mateo; McNames, James (2016-08-11)Background: We describe the first automatic algorithm designed to estimate the pulse pressure variation (PPVPPV) from arterial blood pressure (ABP) signals under spontaneous breathing conditions. While currently there are ... -
The facial inversion effect throughout healthy adult aging : an event-related brain potential study
Williams, Patrick M (East Carolina University, 2019-07-02)Age-associated cognitive decline (AACD) is a natural part of life. The difference between malignant and benign AACD can be difficult to determine in the early stages of dementia. Many factors affect an individual's brain ...
