Description, Abstract, or Artist's Statement
Task-based functional magnetic resonance imaging (t-fMRI) techniques have changed the way scientists probe the neurological mechanisms underlying behavior. However, there are many problems surrounding t-fMRI especially underpowered studies leading to misleading effect sizes. This study is using a recent large data collection study, the Human Connectome Project, to investigate effect sizes in specific regions of the brain involving working memory. Previous studies have come up with relatively small effect sizes due to small sample sizes and large regions of interest (ROI). This study is concentrated on using more precise ROI called parcels to find larger effect sizes.
