Effects Of Anodal Tdcs On Neural Correlates Of Cognitive Control In Mild-To-Moderate Traumatic Brain Injury, Nickolas A. Mertens
Effects Of Anodal Tdcs On Neural Correlates Of Cognitive Control In Mild-To-Moderate Traumatic Brain Injury, Nickolas A. Mertens
Psychology ETDs
Traumatic brain injury is a worldwide epidemic and currently there is no successful treatment to combat the cognitive deficits sustained from a mmTBI. The goal of this analysis is to determine if active tDCS paired with cognitive training can aid in an individual’s recovery on one specific consequence of mmTBI: cognitive control. To examine this novel treatment on cognitive control, EEG was recorded, and FM-theta activity collected from electrode FCz was analyzed. Three analyses were run to address the hypotheses of the present study: 1. A cluster analysis; 2. A series of repeated-measures ANOVAs; and 3. A series of multiple …

Understanding The Learning Benefits Associated With Transcranial Direct Current Simulation Of The Right Ventrolateral Prefrontal Cortex, Benjamin C. Gibson
Psychology ETDs
Previous work has demonstrated that anodal transcranial direct current stimulation (tDCS) applied to the right ventrolateral prefrontal cortex (rVLPFC) is capable of accelerating learning of a threat identification and classification task. However, questions remain as to the cognitive mechanisms underlying this effect, and whether the observed tDCS mediated learning is specific to threatening stimuli or, rather, a more generalizable learning processes. The goal of the current project was to isolate specific aspects of the threat detection task in order to exemplify previous findings. A number of pre-test measures were included to attempt to decipher the characteristics of subjects who are …
Using Brain Stimulation To Enhance Working Memory: A Charged Topic, Michael Christopher Stefan Trumbo
Using Brain Stimulation To Enhance Working Memory: A Charged Topic, Michael Christopher Stefan Trumbo
Psychology ETDs
Although working memory (WM) training programs consistently result in improvement on the trained task, benefit is typically short-lived and extends only to tasks very similar to the trained task. Pairing repeated performance of a WM task with brain stimulation may encourage plasticity in brain networks involved in WM task performance, thereby improving the training benefit. In the current study, transcranial direct current stimulation (tDCS) was paired with performance of a WM task. In Experiment 1, participants performed a spatial location-monitoring n-back during stimulation, while Experiment 2 used a verbal identity-monitoring n-back. In each experiment, participants received either active (2.0 mA) …
