The goal of my study is to test the overarching hypothesis that art therapy is effective because it targets emotional dysregulation that often accompanies significant health stressors. By reducing the salience of illness-related stressors, art therapy may improve overall mood and recovery, particularly in patients with cancer. After consulting the primary literature and review papers to develop psychological and neural mechanisms at work in art therapy, I created a hypothetical experimental procedure to test these hypotheses to explain why art therapy is helpful to patients with chronic illness. Studies found that art therapy stimulates activity of multiple brain regions involved in memory retrieval and the arousal of emotions. I hypothesize that patients with chronic illness have a reduced capacity for emotion regulation, or difficulty recognizing, expressing or altering illness-related emotions (Gross & Barrett, 2011). Further I hypothesize that art therapy improves mood and therapeutic outcomes by acting on the emotion-processing regions of the limbic system, and thereby facilitating the healthy expression of emotion, emotional processing, and reappraisal. More mechanistically, I propose art therapy reduces the perception or salience of stressors by reducing amygdala activity leading to decreased activation of the hypothalamic-pituitary-adrenal (HPA) axis. The art therapy literature and my hypothesis about its mechanisms of action became the basis of my proposed study. To assess the effectiveness of art therapy in alleviating symptoms of chronic disease, I am specifically targeting patients with cancer who exhibit a lack of emotional regulation. Saliva is collected 3 times a week on the day of intervention: morning after waking, afternoon, and evening. Stress levels are tested using one-hour art therapy sessions over the course of 3 months. The Perceived Stress Scale (PSS) assesses an individual's perceived stress and feelings in past and present situations, for the control and intervention group. To measure improvement in overall mood, 10 one-hour art sessions are performed on patients over 10 weeks. A one-hour discussion analyzing the participants' artwork follows each art session. The Spielberger State-Trait Anxiety Inventory (STAI) assesses overall mood for the intervention and control groups. I created rationale and predictions based on the intended results of each experiment.

Abstract White matter thickness correlates with various mental illness. Commissure white matter tracts are responsible for interconnecting the same cortical area in both hemispheres. Injury to the brain can result in thinning and shrinkage even collapsing and detachment of the white matter tracts' myelin sheaths. Injury can affect cognitive function and time points are essential for therapeutic intervention. Research is beginning to identify gradual long-term neurodegenerative effects. With the advancement of brain imaging technology, we know that Wallerian degeneration has a significant negative impact on the white matter tracts throughout the brain (Johnson, Stewart, & Smith, 2013). If major tracts become injured like, the corpus callosum, then it can affect interhemispheric communication. Once myelin is damaged the axon becomes vulnerable, and the mechanisms of nerve recovery are not well known. Myelin sheath recovery has been studied in hopes to proliferate the oligodendrocytes that make up for the atrophied myelin. Neurotoxic chemicals released at activation of macrophages which hinders the brains ability to proliferate myelin protein needed for myelin differentiation adequately. In the central nervous system myelin has mechanisms to recover. Neurogenesis is a naturally occurring recovery mechanism seen after brain injury. Understanding the time points in which brain recovery occurs is important for treatment of diffuse injuries that cannot be identified through some imaging techniques. To better understand critical timepoints of natural recovery after brain injury can allow further investigation for early intervention to promote adequate recovery.
