This paper is devoted towards the origin of a human subjective state, and we present a methodology for studying the origin of brain activity. We were first to reveal that the subjective states of a human being can be subjected to an objective remote registration. Recently we have established the existence of the so-called “psychogenic field”, which reflects the subjective state of human brain. The subjective state of a human being was shown to affect remotely the physicochemical properties of the blood. The interaction of neurophysiological and subjective processes is described in the context of systemic organization of a goal-directed behavior. An original schematic diagram is presented to describe the formation of a subjective brain state. This approach is based on the feedback influence of a psychogenic field on neuronal molecular processes (self-induction in the brain). We propose a paradigm for the origin of a subjective state and possible existence of physical phenomena and brain fields, which are unique for the active brain.
