2.4.2 Cardio-vasculary <strong>and</strong> respiratory regulation<br />
As discussed above, the hypothalamus is the most important regulation<br />
centre. There are regions with parasympathetic <strong>and</strong> sympathetic functions.<br />
When the rostral part of the hypothalamus is stimulated, especially the<br />
praeoptic area, the result is an increased parasympathetic activity involving<br />
sweating, vasodilatation, increased salivation, decrease in blood pressure <strong>and</strong><br />
pulse as well as bladder contractions <strong>and</strong> rising gastrointestinal activity. 18<br />
The centres for respiratory <strong>and</strong> cardiovasculary regulation with autonomous<br />
centres for blood pressure, heart activity, vasodilatation, inspiration <strong>and</strong><br />
expiration, etc. are located on the floor of the fourth ventricle, in the medulla<br />
oblongata. This allows a common regulation of the cardiac <strong>and</strong> respiratory<br />
functions. Various pieces of information from the cortex, other autonomic<br />
centres <strong>and</strong> the periphery are processed in this area.<br />
