the purpose of the present study was to determine whether neuropeptide y ( npy ) acts within the hypothalamic paraventricular nucleus ( pvn ) or the suprachiasmatic nucleus ( scn ) to alter circulating levels of corticosterone and to evaluate the effects of npy on the single-unit response of pvn and scn neurons using the hypothalamic slice preparation .
