Assessing The Effect Of Chronic Dopamine Receptor 2 Blockade As A Potential Model Of Secondary Negative Symptoms In Rats Using The Fr5/Chow Feeding Choice Task, Cyrene Nicholas

Honors Scholar Theses

Haloperidol, a dopamine (DA) D2 receptor antagonist, is an antipsychotic drug which is commonly used to treat schizophrenia and other psychiatric disorders. These disorders are often characterized by elevated striatal dopamine, which is speculated to have a role in producing positive symptoms such as hallucinations, delusions, and paranoia, as well as symptoms related to motivational salience and reward prediction. Individuals with schizophrenia also exhibit negative symptoms, such as amotivation, anergia, fatigue, and apathy among others. While some negative symptoms of schizophrenia are inherent to the pathophysiology, other negative symptoms are hypothesized to be partially induced by chronic exposure to antipsychotic …

Effects Of Lisdexamfetamine And Haloperidol On A Binge-Like Eating Model & Preliminary Investigations Of The Dopaminergic Mechanism Underlying Binge Eating Disorder (Bed), Maxime Braun

Honors Scholar Theses

Binge eating disorder (BED) is a psychophysiological disorder defined as the excessive intake of high-caloric, palatable foods within a short span of time, accompanied by feelings of distress. Animal models of binge-like eating behavior have been developed that give intermittent, limited access to a highly palatable food. Presby et al. (2020) used chocolate as the highly palatable food to induce binge-like eating behavior in rats. Lisdexamfetamine (LDX), a d-amphetamine prodrug and dopamine (DA) uptake inhibitor, is currently used to treat BED in humand. In rats, binge-like eating of chocolate was induced by exposure to unpredictable and limited chocolate access over …
