We measured c-fos messenger RNA levels and Fos protein immunoreactivity in the suprachiasmatic nucleus of rats as a function of light and time of day. Immunohistochemistry demonstrated a daily rhythm of immunoreactive Fos in the ventrolateral subdivision of the suprachiasmatic nucleus of animals entrained to a 12 h/12 h light-dark cycle; expression was low during the dark phase, peaked about 2 h after light onset at dawn, and remained elevated at an intermediate level for the remainder of the… CONTINUE READING
