Effects Of Altered Prenatal Sensory Stimulation On Postnatal Contingency Learning In Bobwhite Quail Neonates (Colinus Virginianus), Namitha Raju
FIU Electronic Theses and Dissertations
Preterm infants are exposed to high levels of modified early sensory experience in the Neonatal Intensive Care Unit (NICU). Reports that preterm infants show deficits in contingency detection and learning when compared to full-term infants (Gekoski, Fagen, & Pearlman, 1984; Haley, Weinberg, & Grunau, 2006) suggest that their exposure to atypical amounts or types of sensory stimulation might contribute to deficits in these critical skills. Experimental modifications of sensory experience are severely limited with human fetuses and preterm infants, and previous studies with precocial bird embryos that develop in ovo have proven useful to assess the effects of modified perinatal …
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 …
