Figure 2.
Acute effects of posterior hypothalamic lesions on LHRH release in the stalk-median eminence. Group means (± SEM) are shown. Number of monkeys in the lesion group and sham/control group were 6 and 5, respectively. Note that lesion resulted in a significant increase in LHRH levels in both morning and evening when compared to the value prior to lesions (within group) as well as to those in the sham/control group at the corresponding age (between groups). In the sham/control group LHRH levels did not change. **: p<0.01 vs. 15–17 months (before lesions, within group); ††: p<0.01 vs. control/sham at the corresponding age (between groups); a: p<0.05 vs. morning values.
