Presenting information to multiple sensory modalities sometimes facilitates and sometimes interferes with processing of this information. Research examining interference effects shows that auditory input often interferes with processing of visual input in young children (i.e., auditory dominance effect), whereas visual input often interferes with auditory processing in adults (i.e., visual domi...

Gonadotropin-releasing hormone 1 (GnRH1) neurons control reproductive activity, but GnRH2 and GnRH3 neurons have widespread projections and function as neuromodulators in the vertebrate brain. While these extra-hypothalamic GnRH forms function as olfactory and visual neuromodulators, their potential effect on processing of auditory information is unknown. To test the hypothesis that GnRH modula...
