Abstract
In vivo microdialysis was used to measure extracellular concentrations of norepinephrine in the diagonal band of Broca (DBB) during changes in blood pressure in conscious rats. Dialysate norepinephrine concentr ation was significantly increased during acute hypertension (280 +/- 4 0% of control), but was not changed by hypotensive hemorrhage. These r esults are consistent with the proposal that noradrenergic innervation of the DBB is selectively activated by increased blood pressure.
