a larger sexually dimorphic nucleus of the medial preoptic area is the result of?
sexual behavior
appetitive behaviors are also partly controlled by medial preoptic area as aromatase-knockout mice show deficits in sexual motivation. however, appetitive behaviors are disrupted by the lesions in rostral part rather than caudal part of medial preoptic area. lesions of the rostral part of medial preoptic area also diminish preference for female by male rats. furthermore, in vivo dialysis experiments showed that the level of extracellular dopamine in the mpoa increases as the sexual appetitive sequences progress. mpoa’s involvement in the control of appetitive sexual behaviors is also confirmed by pharmacological manipulations of the dopaminergic system in it. in rats, lesions to mpoa can eliminate the male copulatory behavior but can only diminish appetitive behavior, which suggests that some other parts of the brain, except for mpoa, are also responsible for sexually appetitive behavior.
sexually dimorphic nucleus
sdn and its homologues exist widely in human, mammal, and some other animal brains, including:









































bullet::::- the third interstitial nucleus of the anterior hypothalamus (inah3) in humans;









































bullet::::- ovine sexually dimorphic nucleus (osdn) in the medial preoptic area/anterior hypothalamus (mpoa/ah) in sheep;









































bullet::::- sexually dimorphic nucleus in the preoptic area (sdn-poa) in rats;









































bullet::::- anterior hypothalamic nucleus (ahdc) in macaques;









































bullet::::- specific area in medial preoptic nucleus (pom) in quails; etc.
