Table 3.

Animals that were untreated, or treated with estrogen plus or minus progesterone injection, prior to microdialysis, to determine the effect of steroid treatment on serotonin concentrations. If the probe location was in the medial basal hypothalamus, then the data from the site was included in the estrogen+progesterone analysis.

^*Dialysis initiated 7 h prior to P injection and 0-7 h serotonin data were used to obtain the average for E only treatment in Figure 3 insert.
