Abstract

Long-term recordings of single SCN units were performed in freely moving rats simultaneously with multiunit recordings and evidence is presented for a daily change in light-responsiveness. SCN light response is high during the night and low during the day. We conclude that this difference is caused by a change in sensitivity, with higher sensitivities at night. Moreover, we demonstrate that the circadian rhythm in SCN light response is the result of the integrated behaviour of similarly behaving single SCN units.
