Development Of Prefrontal Structure And Connectivity In Typical Children And Children With Adhd: Association With Language And Executive Function, Dea Garic Jun 2020

Development Of Prefrontal Structure And Connectivity In Typical Children And Children With Adhd: Association With Language And Executive Function, Dea Garic

FIU Electronic Theses and Dissertations

The structure and connectivity of the prefrontal cortex has been extensively studied for its contribution to language and executive function (EF) development, but many questions still remain whether its microstructural tissue properties can reliably predict behavioral outcomes in very young typically and atypically developing populations. In particular, the bilateral frontal aslant tract (FAT) has garnered increasing interest with respect to its potential association with both language and EF, but has yet to be examined in childhood attention disorders, such Attention Deficit Hyperactivity Disorder (ADHD). At the same time, with advances in diffusion weighted imaging (DWI), new diffusion models offer more …


Fiber Pathways For Language In The Developing Brain: A Diffusion Tensor Imaging (Dti) Study, Iris J. Broce Mar 2014

Fiber Pathways For Language In The Developing Brain: A Diffusion Tensor Imaging (Dti) Study, Iris J. Broce

FIU Electronic Theses and Dissertations

The present study characterized two fiber pathways important for language, the superior longitudinal fasciculus/arcuate fasciculus (SLF/AF) and the frontal aslant tract (FAT), and related these tracts to speech, language, and literacy skill in children five to eight years old. We used Diffusion Tensor Imaging (DTI) to characterize the fiber pathways and administered several language assessments. The FAT was identified for the first time in children. Results showed no age-related change in integrity of the FAT, but did show age-related change in the left (but not right) SLF/AF. Moreover, only the integrity of the right FAT was related to phonology but …
