Odogenic change of blood coagulation in humans.
The blood coagulation time as an integral sign of human homeostasis is revealed to be influenced by conscious or unconscious olfactory stimuli through autonomic mechanisms. The hemostasis of subjects with predominance of sympathetic activity is more sensitive to the olfactory stimuli than that of subjects with vagal prevalence. The effects of the olfactory stimuli upon hemostasis in humans support the viewpoint that simultaneous information and physico-chemical processes act together in parallel to play and important role in life activities of human organism (Simonov, 1981; Sudakov, 1995). Emotions, therefore, are essential in the transfer of information from the environment (Anokhin, 1966; Miltner et al., 1994). It is not excluded that even very weak stimuli which are subthreshold for conscious perception might be informational for the organism as those engaging emotional response.
