UNLV Theses, Dissertations, Professional Papers, and Capstones
Methamphetamine (METH) abuse impacts the global economy through costs associated with drug enforcement, emergency room visits, and treatment. Hyperthermia is a leading cause of METH induced emergency room visits and may lead to neural damage. Previous research has demonstrated early life stress, such as childhood abuse, increases the likelihood of developing a substance abuse disorder. However, the effects of early life stress on neuronal damage induced by chronic METH administration are unknown. We aimed to elucidate the effects of early life stress on METH induced dopamine damage in the striatum. Animals were separated three hours per day during the first …

In order to assess flexibility in acquiring and using conflicting response rules, rats with selective lesions of the NBM or sham-lesion controls were subjected to serial reversal training in a simple operant discrimination paradigm. The NBM lesion group did not differ from the control group in acquisition of the original rules; the NBM lesion group required more time to master the changes in rules in the first reversal, but not in subsequent reversals.

Hemisphere Side Of Damage And Encoding Capacity, Margaret Ellen Davis
Dissertations and Theses
This study was designed to examine whether normal information processing does engage both hemispheres of the brain regardless of sensory channel (i.e., auditory or visual), and whether an opportunity for dual encoding (verbal and visual) was advantageous for patients with unilateral brain damage. It compared memory for verbal material presented in the visual and auditory modalities among three groups: right hemisphere brain damaged stroke patients (RBD), left hemisphere brain damaged stroke patients (LBD), and neurologically intact control subjects.
