Imaging of the intact KNDy neuron population following immunolabelling and optical tissue clearing. (A) Rat brain block before (i) and after (ii) immunolabelling and clearing. (B) Projection (optical thickness = 200 µm) of kisspeptin (red) and neurokinin B (green) immunolabelling imaged through the sagittal plane of the arcuate nucleus of ovariectomized rats implanted with either sesame oil vehicle (OVX + VEH, (B)) or estradiol (OVX + E2, (C)). R = rostral, D = dorsal.
