Multiunit activity (MUA) in the suprachiasmatic nucleus (SCN) and adjacent hypothalamic areas were compared in albino rats anesthetized with thiopental, immobilized with succinylcholine chloride and artificially respired. During adaptation to light lasting up to 2 h, MUA in the SCN increased gradually, whereas MUA in the other locations outside the SCN decreased. During adaptation to the dark, MUA in the SCN decreased whereas MUA outside the SCN increased. This reversal was apparent not only when recording in the SCN and adjacent hypothalamus simultaneously, but also while advancing an electrode from the optic chiasm through the SCN to the anterior hypothalamus.
在使用硫喷妥钠麻醉、氯化琥珀胆碱制动并进行人工呼吸的白化大鼠中，对其视交叉上核（SCN）和相邻下丘脑区域的多单位活动（MUA）进行了比较。在长达2小时的光照适应过程中，SCN中的MUA逐渐增加，而SCN以外其他位置的MUA则减少。在黑暗适应过程中，SCN中的MUA减少，而SCN以外的MUA增加。这种反转不仅在同时记录SCN和相邻下丘脑时明显，而且在将电极从视交叉推进穿过SCN到达下丘脑前部时也很明显。
