A Behavioral And Neuroimmune System Model Of The Effects Of Chronic Low-Level Lead Exposure In Young Male C57bl/6j Mice, Mayra Gisel Flores-Montoya
Open Access Theses & Dissertations
Chronic low-level lead exposure reduces memory in children however the brain mechanisms mediating these effects are not known. In previous studies we showed that early lead exposure reduced olfactory memory and exploratory behavior in young mice, and reduced microglia cell density in hippocampus/dentate gyrus. The present studies aimed to identify additional behavioral tests that were sensitive to early low-level lead exposure in young mice; and to examine whether microglia upregulated factors known to promote cell migration. Seventy-two C57BL/6J male mice were exposed to 0 ppm (controls), 30 ppm (low-dose), or 430 ppm (high-dose) of lead acetate via dams' milk from …
Phonological Memory Associations Of Language Impairment In Bilingual Children, Marcela Susa
Phonological Memory Associations Of Language Impairment In Bilingual Children, Marcela Susa
Open Access Theses & Dissertations
Knowledge-based assessments of language impairments have been found to contain bias for assessing performance in bilingual children from diverse cultural backgrounds. As an alternative, measures related to performance of phonological working memory are becoming more popular for bilingual children. The purpose of the current study was to investigate how bilingual children with language impairment (BILI) would perform on nonword repetition and sentence repetition when compared to typically developing peers (BITD). Also, the current study investigated the extent to which the nonword repetition task and sentence repetition task were associated with each other in bilingual (English-Spanish) children. Results demonstrated that typically …
