To develop more effective treatments, it is crucial to understand why individuals with BPD engage in anger rumination despite its negative outcomes. The activation of energy associated with anger, as well as feelings of justification and validation, may be experienced in the short-term as rewarding. This may prevent individuals with BPD from attempting to reduce their rumination.

Functional magnetic resonance imaging (fMRI) and behavioral methods were utilized to examine this theory in a sample …

Neuropsychological Correlates And Underlying Cortical Mechanisms Of Working Memory In Moderate To Severe Traumatic Brain Injury, Jessica Ann Clark

University of Kentucky Doctoral Dissertations

Functional magnetic resonance imaging (fMRI) is a relatively new tool that has been used to examine patterns of neural activation within those with traumatic brain injuries (TBI). A review of relevant literature is presented, including alterations in activity within the frontal and parietal regions that are thought to be compensatory in nature. In addition, possible explanations for discrepancies within this research are discussed. The current study expands upon previous work by incorporating a delayed-match-to-sample (DMS) task within an event-related paradigm and neuropsychological testing to compare 12 individuals with a history of TBI to 12 control participants with orthopedic injuries (OI). …
