  • Look Inside

1. The angio-architecture of the cerebral ar- teries, especially of the basial artery filled with synthetic resin improved by Motozato was studied in men and dogs, and the aut- hors confirmed that there existed the ar- terial anastomoses among the arteries of the cerebral cortex but there were no such anastomoses among the perforating arteries of the brain stem and of the basal ganglia.

2. Administration of some central nerve sti- mulants such as Picrotoxin, Ephedrin, KCl or Nicotin into the vertebral artery of ra- bbits caused more easily a pressor response than a depressor one, that is, the sympa- thetic function was dominant but adominist- ration into the carotid artery, on the contr- ary, more easily caused a depressor, i.e. parasympathetic response than a sympathetic One.

3. In rabbits and cats, the effect of the mechanical occlusion of the basial artery on the blood pressure and respiration was ob- served, through a parapharyngeal approach after ligation of both carotids.

a) Occlusion at the rostral level caused inhibition of respiration and a marked rise in blood pressure in all cases.
