Abstract

The present study, utilizing rat brain slice of the suprachiasmatic nuclei (SCN) demonstrated single neuronal activity of SCN cells which changed in correspondence to environmental light-dark (L-D) schedules. The unit discharge rates of cells from animals kept on normal LL-D) cycles reached peaks at about 14.00 h and had a lowest point at around 02.00 h. The unit activity in slices from animals kept on reversed (L-D) cycles was shifted approximately 12 h.
