Changes in plasma LH levels and the number of FLI cells within the basal hypothalamus in castrated quail after resonance cycle treatment. Exposure to three cycles of 10L:26D was highly inductive in terms of LH secretion, with the change being from −1.04 (± 0.61 ng/ml; n = 6) to 5.66 (± 2.33 ng/ml;n = 6; **p < 0.01). The number of FLI cells was significantly increased after 10L:26D (unpairedt test, t = −2.94; *p < 0.05).
