Assessing The Impact Of Lipopolysaccharide On Learning And Memory In Rats, Anahat Luthra

Undergraduate Student Research Internships Conference

The immune system and the central nervous system (CNS) have a bi-direction relationship, modulating one another.⁴ Proinflammatory cytokines released from CNS immune cells have an impact on cognitive processes such as learning and memory.¹ Liposaccharide (LPS), a cell wall component of Gram-negative bacteria, which is used to activate proinflammatory cytokine release has been found to impact learning and memory processes, such as in the anticipatory nausea paradigm (ANP).² Anticipatory nausea and vomiting is that which may occur before a chemotherapy treatment session begins in a patient who has had chemotherapy before. It is caused by triggers like …

The Effects Of The Aromatase Inhibitor, Letrozole, On Lithium Chloride (Licl)-Induced Conditioned Disgust Behaviour (Anticipatory Nausea) In Male Rats, Vangel Matic

Undergraduate Student Research Internships Conference

Anticipatory Nausea (AN) is a form of classical conditioning in which the effects of a nausea-inducing toxin become associated with a specific environmental context. AN is often experienced by individuals receiving chemotherapy treatment, whereby the emetic effects of the chemotherapy agents become associated with the treatment context (i.e. hospital, clinic), such that exposure to the context alone can cause an individual to experience nausea and potentially withdraw from treatment. Chemotherapy-associated AN is suggested to have a higher incidence in females compared to males.

AN can be represented in a rodent model (conditioned disgust) through the occurrence of conditioned gaping behaviour …

Oxytocin Does Not Mediate Lithium Chloride (Licl)-Induced Non-Social Environmentally Conditioned Disgust Behaviour (Anticipatory Nausea) In Male Rats, Vangel Matic

Undergraduate Student Research Internships Conference

Introduction. Anticipatory Nausea (AN) is a form of classical conditioning in which the effects of a nausea-inducing substance, such as lithium chloride (LiCl), become associated with a social or environmental context. In rats, AN can be measured by the frequency of conditioned gaping behaviour, displayed when rats are re-exposed to a context previously associated with LiCl. Oxytocin (OT) may be involved in the mediation of socially conditioned disgust, though its role in mediating non-social environmentally conditioned disgust is unclear. The purpose of the present study was to investigate the role of OT in mediating environmentally conditioned disgust. It was hypothesized …
