Examples of CLSM images of NMDAR1 immunolabeled dendrites in the CA1 subfield of an OVX rat (A), an OVX+E rat (B), and an OVX+E+P rat (C). Note the presence of punctate staining within the cytoplasm of the dendritic segments (see Discussion) and the increased intensity of staining within the CA1 dendrites of the steroid-treated ovariectomized rats (B,C) rats compared with the nonsteroid-treated ovariectomized rats (A). Scale bar, 10 μm.
