[Sensitivity of neurons in the rabbit thalamus parafascicular complex to angiotensin II during stimulation of the ventromedial hypothalamus].

A study was made of the sensitivity of parafascicular neurons of the thalamus to angiotensin II (A-II) applied microiontophoretically. Almost half of the neurons investigated (48,5%) were discovered to be sensitive to the peptide. Stimulation of the ventromedial hypothalamus provoked marked changes in the pattern of the responses of parafascicular neurons of the thalamus to A-II. The data obtained suggest that the sensitivity of parafascicular neurons of the thalamus, the pattern of responses to biologically active substances may be altered dynamically under the influence of excitations evoked by stimulation of the hypothalamus.
