Correlation Of The Anterior Salience Network With Attention: A Resting-State Fmri Analysis, Matthew Brooks May 2022

Correlation Of The Anterior Salience Network With Attention: A Resting-State Fmri Analysis, Matthew Brooks

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Background: Some studies have broadened our understanding of attention while other studies have used resting-state functional magnetic resonance imaging (fMRI) analyses to identify brain regions that are functionally connected and may be associated with salience processing. This thesis sought to examine the relationship between the anterior salience network and attentional control. The current study hypothesized that resting-state functional connectivity between regions of the anterior salience network would be associated with attentional control ability. Methods: Forty-eight college-aged students completed the affective Stroop task to assess attentional regulation ability. Accuracy on trials of the task was examined in correlation with resting-state functional …

The ability to represent approximate quantities appears to be phylogenetically widespread, but the selective pressures and proximate mechanisms favouring this ability remain unknown. We analysed quantity discrimination data from 672 subjects across 33 bird and mammal species, using a novel Bayesian model that combined phylogenetic regression with a model of number psychophysics and random effect components. This allowed us to combine data from 49 studies and calculate the Weber fraction (a measure of quantity representation precision) for each species. We then examined which cognitive, socioecological and biological factors were related to variance in Weber fraction. We found contributions of phylogeny …
