Many species are sexually dimorphic: differences in size, anatomy, morphology, physiology, and behavior can affect reproduction and development, stress response, health, aging, and other traits. Such characteristics, governed by the brain, are often prioritized between survival and reproduction during the individual’s sexual viability. Considering the physiological and behavior differences of females and males in reproduction, priorities of each sex are also likely to differ.  Since brain gene expression often precedes measurable morphological and physiological variation between sexes, we study the brain transcriptome to better understand biologically relevant sex-specific temporal shifts in gene activity and resulting physiological phenotypes at comparable reproductive life stages.
