Schizophrenia- Like Attentional Deficits Following Blockade Of Prefrontal Cortex Gaba(A) Receptors, Tracie A. Paine, Lauren E. Slipp, William A. Carlezon Jr.

Faculty & Staff Scholarship

Attentional deficits are a core symptom of schizophrenia. Post-mortem analyses of the brains of schizophrenics reveal consistent abnormalities in gamma-aminobutyric acid (GABA) interneurons indicative of reduced cortical GABA transmission, raising the possibility that this pathology contributes to attentional deficits. We examined whether blockade of prefrontal cortex (PFC) GABA(A) receptors with bicuculline (BMI) impairs attention in rats using the 5-choice serial reaction time task (5CSRTT). For comparison, we also examined whether administration of the GABA(A) receptor agonist muscimol (MUS) would improve attention. In parallel, we examined the effects of both manipulations on activity in an open field and on motivation using …

The Neuropsychological Effects Of Combined Physical And Mental Exercise In Schizophrenia, Maggie M. Manning

Honors Theses

People suffering from severe mental disorders encounter many debilitating side effects. Those diagnosed with schizophrenia face a large number of challenges each day. Not only must they endure symptoms, like hallucinations and delusions, commonly associated with the illness, but their higher-level cognitive functioning is further impaired in numerous ways. People with schizophrenia, suffering from thought disorder, battle with a pattern of disorganized thinking in which seemingly simple tasks, i.e attention and memory, are difficult. Negative symptoms include the inability to establish social relationships, and hinder their everyday experiences, including work. Their extremely sedentary lifestyle also negatively impacts engagement in other …

Mglur5 Involvement In Methamphetamine Reward And The Co-Morbidity Of Schizophrenia And Stimulant Use Disorders, Amy Anne Herrold

Dissertations (2 year embargo)

Methamphetamine (Meth) is a potent, widely-used stimulant. Stimulant abuse occurs more frequently in the schizophrenia patient population than the general population. The co-morbidity of stimulant use disorders and schizophrenia presents an understudied phenomenon and suggests overlapping brain states of these two pathologies.

There are currently no FDA-approved pharmacotherapies for Meth addiction and relapse to Meth use remains a substantial challenge for abstinent Meth addicts. One factor that contributes to craving and relapse is exposure to environmental or contextual cues associated with Meth use. This effect is the consequence of associative learning that occurs between the rewarding properties of drugs and …
