Estradiol and song affect female zebra finch behavior independent of dopamine in the striatum.

Physiology & Behavior 2009 October 20
Female songbirds display preferences for certain song characteristics, but the neural and hormonal mechanisms mediating these preferences are not fully clear. The present study sought to further explore the role of estradiol, as well as assess potential roles of dopaminergic systems, on behavioral responses to song. Adult female zebra finches were treated with estradiol and exposed to tutored or untutored song or silence. Behavior was quantified and neurochemistry of the nucleus accumbens and striatum was examined with high performance liquid chromatography. As a control, the responses of these two systems to treatment with raclopride, a specific D2 receptor antagonist, were also evaluated. This manipulation did not affect dopamine (DA), but did increase DOPAC and the DOPAC/DA ratio. Estradiol reduced the display of two behaviors, distance calls and visual scanning, but had no effect on dopaminergic responses. Auditory stimulus exposure affected other vocalizations, but song presentation did not modulate the levels of DA or its metabolite, DOPAC in the nucleus accumbens or striatum. Collectively, the results suggest that both estradiol and auditory stimuli can modify the behavioral responses of adult zebra finches, but they may not change DA concentration or turnover in striatal dopamine neurons.
