Description
To investigate which brain regions are involved in the anticipatory activity in rats restricted feeding for 2 hr, we examined c-Fos expression before and after feeding. Only the thalamic paraventricular nucleus (tPVN) showed c-Fos expression before feeding than after feeding. After the anticipatory locomotor activity rhythm was established, lesioning the tPVN attenuated this rhythm, but not the light-dark entrained rhythm. The anticipatory increase of blood corticosterone levels was not established in long-term tPVN-lesioned rats. These results suggest that the tPVN is involved in the expression of anticipatory reactions under a food-restricted regimen.<br>
