Presentation Title: The Effects of Prefrontal Inhibitory Signaling on Spatial Working Memory in a Rat Model for Schizophrenia

Section: Poster Session Group 2 2

Location: , Great Hall

Date & Time: Friday, April 19, 2013 - 2:45pm - 3:30pm


Schizophrenia is a chronic and debilitating disorder that can greatly impair cognitive function, including working memory and cognitive flexibility. Recent research has linked these impairments to reduced inhibitory signaling by the neurotransmitter GABA within the prefrontal cortex. Our study tested the ability of a positive modulator of GABA activity, TCS-1205, to reverse working memory impairments induced by the NMDA receptor antagonist MK-801. MK-801 impairs cognition, in part by reducing GABA neuron activity, and is used as a model of schizophrenia. We injected MK-801 into the prefrontal cortices of adult male Sprague Dawley rats. Following drug injections, rats were tested for spontaneous alternation behavior, a measure of spatial working memory. We have seen a small decrease in spontaneous alternation performance in the treatment group given MK-801 when compared with the control group. Contrary to our working hypothesis, this decrease has been more pronounced in the groups given MK-801 and TCS-1205 simultaneously.
