Figure 5From: Regulatory mechanisms of testosterone-stimulated song in the sensorimotor nucleus HVC of female songbirdsTestosterone stimulated the growth of the vascular bed in the HVC of female European robins. Photomicrographs of the HVC were prepared from control (A) and testosterone-treated (B) female robins and stained with an anti-laminin antibody. The ventral border of HVC was detected by a DAPI (4′,6-diamidino-2-phenylindole-dihydrochlorid) counterstain (data not shown) and is indicated by a dashed line; scale represents 500 μm.Back to article page
