Cerebellum-Seeded Functional Connectivity Changes In Trait-Anxious Individuals Undergoing Attention Bias Modification Training, Katherine Elwell
Cerebellum-Seeded Functional Connectivity Changes In Trait-Anxious Individuals Undergoing Attention Bias Modification Training, Katherine Elwell
All NMU Master's Theses
Anxiety and anxiety related disorders are increasing at a drastic rate in the past decade, with the NIMH reporting that 31.1% of U.S. adults will experience an anxiety disorder at some point in their lives. Anxiety is commonly characterized by increased attention bias to threat. Attention Bias Modification (ABM) is a new treatment used to reduce individual’s attention bias towards threat. The extent to which ABM leads to underlying neural changes is still unknown. The cerebellum is a neglected brain structure, with new research provides evidence that cerebellum’s functional connectivity and shared networks with threat processing regions has a direct …
Electrocortical Changes Observed In The N2 As An Outcome Of Attention Bias Modification Training, Hayley Gilbertson
Electrocortical Changes Observed In The N2 As An Outcome Of Attention Bias Modification Training, Hayley Gilbertson
All NMU Master's Theses
Anxiety disorders are currently one of the most predominant mental health conditions worldwide. Increased anxiety is associated with elevated attentional focus to threat also known as attentional bias to threat. Attention Bias Modification (ABM) is a type of computerized training, attempting to reduce attentional focus for threatening stimuli and has been found to successfully reduce symptoms of anxiety. Past studies have implemented ABM training as a possible tool to modulate attention away from threat in attempt to decrease pathological anxiety. The N2 is an event-related potential (ERP) detected in scalp EEG recordings that is associated with conflict monitoring and complex …
Evaluating Changes In Error-Monitoring Electrocortcial Responses As An Outcome Of Attention Bias Modification Training, Jeremy Andrzejewski
Evaluating Changes In Error-Monitoring Electrocortcial Responses As An Outcome Of Attention Bias Modification Training, Jeremy Andrzejewski
All NMU Master's Theses
Anxiety disorders are among one of the most debilitating and prevalent mental disorders. Maladaptive anxiety has been associated with enhanced attention bias to threat as well as heightened error-monitoring following an erroneous response. In an effort to reduce an anxious individual’s attention bias to threat, an attention training paradigm known as attention bias modification (ABM) was developed. While ABM training has demonstrated the ability to reduce attention bias and anxiety symptoms, there are inconsistencies in the magnitude of symptom reduction and there is a lack of neuroimaging support in regards to ABM outcome. Therefore, this study evaluated the outcome of …
Evaluating The Use Of Self-Relevant Stimuli In Attention Bias Modification Training As A Treatment For Anxiety: A Near-Infrared Spectroscopy Study, Jacob Scott Aday
Evaluating The Use Of Self-Relevant Stimuli In Attention Bias Modification Training As A Treatment For Anxiety: A Near-Infrared Spectroscopy Study, Jacob Scott Aday
All NMU Master's Theses
Increased attentional bias to threat has been identified as a causal mechanism in the development of anxiety. As such, attention bias modification (ABM) was conceived as a treatment option where anxiety is alleviated through a computerized cognitive training regimen that reduces an individual’s attentional bias to threat. However, few studies to date have examined how to tailor ABM treatments to unique individuals and how that may facilitate greater generalization of treatment effects in the real world. Additionally, the neural mechanisms underlying ABM are poorly understood. The participants in this study gave a list of the 10 things that caused them …
Effects Of Optogenetic Activation And Pharmacological Modulation Of Dopamine Neurons, Remington J. Rice
Effects Of Optogenetic Activation And Pharmacological Modulation Of Dopamine Neurons, Remington J. Rice
All NMU Master's Theses
This study explored the use of optogenetic tools to better understand treatments used for schizophrenia. The “positive” symptoms (e.g., hallucinations, paranoia, etc.) of schizophrenia may come from overexpression of dopamine in mesolimbic dopamine neurons. Positive symptoms can be produced in healthy volunteers treated with amphetamine, a psychostimulant drug and dopamine releaser. Conversely, antipsychotic drugs may reduce positive symptoms by blocking dopamine receptors. This study used optogenetics to explore how drugs that alter neurotransmission, might alter behaviors occurring from activation of mesolimbic dopamine (DA) neurons in the ventral tegmental area (VTA). Light-induced activation of DA neurons in the VTA in male …
