Is Sexual Motivational State Linked to Dopamine Release in the Medial Preoptic Area? H. K. Kleitz-Nelson Johns Hopkins University J. M. Dominguez University of Texas at Austin C. A. Cornil University of Liege G. F. Ball Johns Hopkins University Hypothesis: in this experiment, researchers questioned if sexual motivational state is linked to dopamine release in the medial preoptic area. Participants: 21 adult male Japanese quail and 15 female stimulus quail were used in this experiment and they were experimentally and sexually naive prior to experimental procedures. Results: Extracellular dopamine significantly increased in the presence of a female and returned to baseline after removal of the female. Quail that failed to copulate did not display this increased release. These findings indicate that it is not solely the presence of a female that drives dopamine release in males, but how a male responds to her. In quail that copulated, dopamine release did not change in samples collected during periods of no copulation.
