[Role of diencephalic structures in the regulation of cerebral blood flow].

The effects of electric stimulation of the thalamus, hypothalamus and septum upon the CBF, pO2 of brain tissue, EEG, general arterial pressure and pneumogram, were studied in 74 rabbits with implanted cerebral electrodes. The stimulation mostly resulted in an increase in local blood flow sometimes accompanied by a decrease in cortical blood flow. Other parameters under study changed infrequently and insignificantly. The regulation of the CBF seems to be maintained by intracerebral mechanisms.
