Influence of female odors on lateral hypothalamus in the male rat. Semiquantitative deoxyglucose analysis.
The uptake of 14C deoxyglucose (2DG) has been studied in various hypothalamic and limbic structures of male rats exposed to female odors. Uptake differences were visualized by image processing and quantified by measurement of optical density ratios. With respect to the control group, an increase in uptake was observed in the lateral hypothalamic area (LHA), not only in the olfactory bundle, but also, and more obviously, in the parafornical part. This 2DG response is not a result of an odor-induced general motor activation, although it seems to depend on the behavioral reaction of the animal towards the odor. A similar correspondence was not observed for the 2DG response to odor in the ventromedial hypothalamus. Observations in the medial preoptic area, in the corticomedial amygdala, in the lateral septum, or in the dorsomedial hypothalamus did not reveal any significant change in 2DG uptake.
