This literature review explores the neurocognitive effects of the bilingual brain. Many areas of bilingualism are examined such as age of acquisition, which is when the second language is attained, and memory. The three types of bilingual memory are implicit memory, which is procedural memory, explicit memory, which is declarative memory, and episodic memory, which is autobiographical memory. In relation to the bilingual brain, cognition, control, and /lateralization are also reviewed. Finally, second language (L2) learning strategies are considered. The objective of this study is to obtain an understanding on how two or more languages are acquired and processed in …
A Mouse Model Of Toluene Abstinence-Induced Pathology, Sean Callan
A Mouse Model Of Toluene Abstinence-Induced Pathology, Sean Callan

The intentional misuse of volatile solvents is a persistent public health concern. Limited self-report data suggests that chronic inhalant abusers experience withdrawal symptoms including anxiety and seizure symptoms. However, these symptoms have never been explored in a preclinical model and are not considered part of the DSM-V criteria for an Inhalant Use Disorder. For this experiment, 76 young adult male Swiss Webster mice were exposed to either 5,000 ppm toluene vapor or air (0 ppm) for 24 consecutive hours beginning on postnatal day (PND) 30. Following the 24 hour exposure, mice were allowed to recover for 3 hours before behavioral …

Age-Related Changes In Hippocampal Arc Expression Following Minimal Behavioural Induction, Irina V. Odintsova

Normal ageing is associated with significant changes in cognitive function, including the decline of some forms of memory. The hippocampal formation is critical to learning and memory function, and plasticity in this region declines with age. Additionally, age-related differences in plasticity are greatest at lower levels of stimulation, thus peri-threshold plasticity may be of the greatest relevance for age-related changes in cognition. Moreover, the hippocampus is prone to changes in the expression of gene products that mediate plasticity with age. The current thesis attempts to link these observations by measuring hippocampal expression of Arc, an immediate-early gene that is critical …
