Integrity

Execution of the functions of the nervous system in humans, especially the higher functions of the brain, requires a particular level of stability of the internal environment of the brain. In the resting stage, both the brain and the kidneys are of key importance for homeostasis and take about 20% of the minute volume of blood circulation. Vasopressin has a role in regulating water and ion transport in the kidneys and this same hormone determines different types of behavior. This article pays particular attention to the problem of integrity and its physiological sense. Similar levels of functional organization of the brain and kidneys are identified and we discuss the question of how the integration of molecular and cellular systems generates a new quality – the integrity of the body – is reflected in psychology and creativity.
