Despite a growing body of research demonstrating the value of using evidence-based programs and practices (EBPPs) to address health and education issues, the gap between research evidence and practice in education and human services continues to be a vexing problem. Technical assistance (TA) is widely accepted as a key strategy to support evidence-based programs and practices (EBPP) uptake and implementation. However, little is known about how TA practices are used in TA delivery.

Violent extremism in the United States has surged over the past 25 years, with attacks on and threats to major governmental and other institutions, infrastructure (e.g., electric grid), and specific segments of the population, including immigrant and BIPOC (Black, Indigenous, and other People of Color) communities.

The ventral visual stream is organized into units, or functional regions of interest (fROIs), specialized for processing high-level visual categories. Task-based fMRI scans ("localizers") are typically used to identify each individual's nuanced set of fROIs. The unique landscape of an individual's functional activation may rely in large part on their specialized connectivity patterns; recent studies corroborate this by showing that connectivity can predict individual differences in neural responses.

Article Synopsis
  • Convergence insufficiency (CI) is when your eyes don't work together well when looking at things close up, making reading difficult.
  • Researchers looked at how CI affects a part of the brain called the arcuate fasciculus, which helps with reading.
  • They found that people with CI had smaller and different structures in this brain area compared to those with normal vision, suggesting that CI might change the brain over time due to reading problems.

Advances in functional MRI (fMRI) allow mapping an individual's brain function in vivo. Task fMRI can localize domain-specific regions of cognitive processing or functional regions of interest (fROIs) within an individual. Moreover, data from resting state (no task) fMRI can be used to define an individual's connectome, which can characterize that individual's functional organization via connectivity-based parcellations.
