From: Changes in the 5-HT2Areceptor system in the pre-mammillary hypothalamus of the ewe are related to regulation of LH pulsatile secretion by an endogenous circannual rhythm

Figure 2

Frequency distribution of labelled neurons in frontal brain sections after in situ hybridization with riboprobes against sheep 5HT2 A -receptor, according to the number of silver grains per neuron, in the premammillary hypothalamus of Ile-de-France ewes during the establishment of refractoriness to short days (experiment 1). Closed and open symbols depict ewes with high or low LH pulsatile activity, respectively.
