Fig.2. Mean firing frequency of vasopressin-positive, vasopressin-negative, and non-characterized neurons analyzed in the in vitro dorsal SCN of the rat.

Fig.2

The firing frequency was determined in hypothalamic slices at either CT5–8 or CT14–17. All groups showed a significant effect of diurnal timing. However, the difference was only two-fold in the vasopressin-negative neurons, whereas it amounted to five- or six-fold in the vasopressin-positive neurons. Especially the nocturnal firing frequency rate of vasopressin-positive neurons was remarkably lower as compared to the other groups.
