^aValues are expressed as a percentage of the mean amplitude of MUA volleys observed before the injection on the experimental day.

^bThe area under the curve (AUC) of LH concentrations. Values are expressed as percentage of the AUC during the 1 h period before the injection.

^cMUA data were analyzed in only four goats because electrical noise prevented accurate analysis in one animal.

*p < 0.05 and

**p < 0.01 versus vehicle control.
