Activity Bioelectric Spontaneous

**Spontaneous bioelectrical activity** is a set of bioelectrical signals that arise in the body without stimulation visible or felt by a person. These signals can be recorded using electrodes placed on the skin or inside the body. In general, bioelectrical activity reflects the interaction of various physiological processes and conditions in the human body, including respiration, heart rate, nerve transmission, muscle activity, etc.

Spontaneous bioelectrical activities have different characteristics that depend on the specific tissue or organ. They may be irregular or regular, periodic or chaotic, high amplitude or low amplitude, etc. Despite the wide range of possibilities, common features of spontaneous bioelectrical activity include more or less constant oscillation frequencies, their existence beyond the limits of visible, sound or sensitive stimulation or movement, and persisting identical manifestation even during sleep.

Outside the nervous system (eg, muscles, heart, lungs), there is likely a major generator due to the weak signals emitted by the entire body. Some researchers theorize that these weak signals may lead to stimulation of other parts of the body and create circadian rhythms with common wake-up and bedtimes. Others base their research on the use of computer methods. Mathematical modeling of these

Bioelectrical spontaneous activity (BA) is a set of bioelectrical potentials of the brain that occurs in the absence of visible external stimulation and is not associated with external or internal sensory stimuli. This activity can be recorded as an interference encephalogram (EEG), which records changes in electrode potentials on the surface of the scalp.

As you know, the brain actively interacts with the outside world through various sensory systems, such as vision, hearing, touch, etc. When a person is in a quiet or resting state, the brain generates a series of spontaneous oscillatory patterns known as bioelectrical or spontaneous BA. However, AD can be recorded not only in humans, but also in other species of living beings, including animals and even in the culture of prehistoric peoples.

BA research suggests that this activity is integral to normal brain function and can be used to understand physiological processes associated with
