The content of human physiology as an independent part of current physiology is discussed. Substantiated is the point that subjects of human physiology are not only special sections of physiology where functions are inherent only in human (physiology of intellectual activity, speech, labor, sport), but also in peculiarities of functions, specificity of regulation of each of physiological systems. By the example of physiology of kidney and water-salt balance there are shown borders of norm, peculiarities of regulation in human, new chapters of renal physiology which have appeared in connection with achievements of molecular physiology.

Comparative Study[EEG changes in comparison of rest states with open and closed eyes in complete darkness].
There are visible changes in EEG in transition from an awake resting state with eyes closed (REC) to an awake resting state with eyes opened (REO). These changes are usually treated as reflexion of brain activity reorganization in reply to visual perception. In present investigation we examined EEG records in awake resting states with opened and closed eyes in complete darkness. 30 healthy volunteers participated in this investigation. ⋯ EEG spectral power and coherence analysis demonstrates that REC and REO states differ even if the comparison corresponds to a situation of complete darkness. The differences are significant in any of the frequency ranges delta, theta, alpha1, alpha2, beta1, beta2, gamma. As compared states REC and REO don't differ neither by external visual information nor by illumination level therefore we presumably consider observed EEG changes as correlated with involuntary shift of anticipatory attention from interoceptive state with eyes closed to exteroceptive state with eyes opened.
