Glutamate receptor immunoreactivity in the rat suprachiasmatic nucleus.
Antibodies selective for the glutamate receptor subunits GluR1 and GluR2/3 were used to localize glutamate receptor immunoreactivity in the rat suprachiasmatic nuclei (SCN). These antisera identified two distinct cell populations within the SCN. Cells immunoreactive to GluR2/3 antiserum were located predominantly in the ventral SCN while antiserum selective for GluR1 stained a population located along the dorsal and lateral borders of the nucleus. There were no apparent day-night differences in GluR immunoreactivity observed in the SCN.
