Abstract Objectives The purpose of this study was to investigate the characteristics of physician diagnosed Neurological Lyme disease (NLD) using Quantitative EEG and the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). We hypothesize that findings would include more slow wave (Delta/Theta) activity that is consistent with the severity reported dysfunction. Methods Subjects consisted of four adult females with a physician provided diagnosis of NLD. EEG was recorded from 21 sites during an eyes open and eyes-closed resting conditions. Raw EEG data was made quantifiable (qEEG) through Fourier transformation to determine z-score derived cortical and subcortical slow wave activity. The RBANS was used to assess each subject’s functioning. Results (See Imaging). Subject 1. Theta: 3.7. Alpha: 2.3. Theta: 3.2. Alpha: 2.5. RBANS - 96. Subject 2. Theta: 1.9. Alpha: 3.1. Theta: 2.3. Alpha: 4.4. RBANS - 76. Subject 3. Theta: 3.4. Alpha: 2.8. Theta: 3.5. Alpha: 2.1. RBANS - 110. Subject 4. Theta: 3.6. Alpha: 3.0. Theta: 3.3. Alpha: 2.8. RBANS - 100. Conclusions NLD subjects within this study all demonstrated elevated subcortical frontal and frontotemporal theta and alpha. Elevation in cortical slow wave activity was found for subjects with greater reported symptomatology and may suggest either less severe course of disease or serve as a recovery marker. RBANS assessment variables were not completely sensitive in detection of subject reported challenges. Implications for conceptualization, treatment, and disease monitoring are highlighted. Directions for future research will also be discussed.

Abstract. Working memory supports our ability to maintain goal-relevant information that guides cognition in the face of distraction or competing tasks. The N-back task has been widely used in cognitive neuroscience to examine the functional neuroanatomy of working memory. Fewer studies have capitalized on the temporal resolution of event-related brain potentials (ERPs) to examine the time course of neural activity in the N-back task. The primary goal of the current study was to characterize slow wave activity observed in the response-to-stimulus interval in the N-back task that may be related to maintenance of information between trials in the task. In three experiments, we examined the effects of N-back load, interference, and response accuracy on the amplitude of the P3b following stimulus onset and slow wave activity elicited in the response-to-stimulus interval. Consistent with previous research, the amplitude of the P3b decreased as N-back load increased. Slow wave activity over the frontal and posterior regions of the scalp was sensitive to N-back load and was insensitive to interference or response accuracy. Together these findings lead to the suggestion that slow wave activity observed in the response-to-stimulus interval is related to the maintenance of information between trials in the 1-back task.
