Abstract

The paper deals with spreading of the positive wave (P-wave), appearing in response to stimulation of the basal preoptic area (BPA) in the structures of meso-diencephalic and bulbar levels, predominantly involved into synchronizing and desynchronizing brain systems. It is shown that P-wave is mostly pronounced in the structures situated along the medial fascicle of the forebrain, its bilateral coagulation leading to changes in wave characteristics in the studied structures. Besides, after section of the medial fascicle of the forebrain pronounced inhibitory effects of the posterior hypothalamus on P-wave appearing in response to stimulation of BPA, are considerably weakened.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
