The Developmental Plasticity Of Fruit Fly Vision, John Paul Currea
The Developmental Plasticity Of Fruit Fly Vision, John Paul Currea
FIU Electronic Theses and Dissertations
In this dissertation we explore the morphological and neural plasticity underlying vision at different scales—within and between species of Drosophila—to elucidate the role of eye development in the evolution of vision. In chapter 2, we offer a tool to accelerate large-scale research into compound eye morphology, and validate it on the eyes of several insect orders and image media. Then, in chapter 3 we demonstrate the developmental plasticity of eye morphology and neural summation in fruit flies, finding an interesting interplay between the two systems. In chapter 4, we elucidate the role of visual plasticity and neural summation in the …
The Development Of Spatial Vocabulary, Rosalie Odean
The Development Of Spatial Vocabulary, Rosalie Odean
FIU Electronic Theses and Dissertations
Previous research has shown a link between the spatial words children use and their performance on spatial reasoning tasks. There is a dearth of measures of spatial language, especially those that focus on a specific type of word. This dissertation introduces three studies, using two measures of dimensional adjective comprehension, one in English and one in Spanish. Study one found that bilingual children’s knowledge of dimensional adjectives in one language is not predictive of their performance on dimensional adjectives in the other language, but that general vocabulary within a language predicts performance in that language. This study also showed that …
Fiber Pathways For Language In The Developing Brain: A Diffusion Tensor Imaging (Dti) Study, Iris J. Broce
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 …
Effects Of Increased Levels Of Prenatal Mesotocin On Postnatal Individual Recognition And Stress Responsiveness In Northern Bobwhite Quail (Colinus Virginianus), Brittany Yusko
FIU Electronic Theses and Dissertations
Oxytocin (OT) plays a key role in the mediation of social and stress behaviors across many species; however, the mechanism is still unclear. The present study investigated the influence of prenatal levels of mesotocin (MT; avian homologue of OT) on postnatal social and stress behavior in Northern bobwhite quail. Experiment one determined endogenous levels of MT during prenatal development using an enzyme-linked immunoassay kit. Experiment two examined the influence of increased MT during prenatal development on chicks' individual recognition ability and stress response to a novel environment. Experiment one showed MT levels increased significantly throughout embryonic development. Experiment two showed …
