N normal phenotype
• the inhibition ratio is significantly attenuated compared to wild-type controls
• treatment with fluoxetine restores latent inhibition
• when presented with a novel and a familiar object exploring ration for the novel object is significantly lower than in wild-type mice
• increase in the amplitude of the acoustic startle response
• however, the habituation ratio is similar to controls
• over multiple trials investigation time of an initially novel ovariectomized mouse declines much more slowly than in wild-type mice

nervous system
• decrease in glutamate induced serotonin release from hippocampal slices
• decrease in glutamate induced serotonin release from hypothalamic slices
• however, release in response to maximal stimulation with K+ is similar to wild-type controls

• in the hypothalamus, hippocampus, and hindbrain
• however, levels of 5-HIAA, a serotonin metabolite, are similar to controls, suggesting impaired serotonin release
