WE LIVE IN A WORLD WHERE THERE IS A VACCINE FOR CANCER , but even supermodern methods, technologies and innovations can not slow down the development of viruses: every month we hear about new or treatment-resistant old infections – and it is difficult not to panic in such conditions. We are looking into why

A significant proportion of all the energy expended by the brain goes to the creation and maintenance of membrane potentials of nerve and glial cells, as well as to the transport of substances through the

Headache is pain in any region of the head. Headaches may occur on one or both sides of the head, be isolated to a certain location, radiate across the head from one point, or have

Positron emission tomography (PET ) allows computer visualization of biochemical processes in the tissues of the body and is used in diagnostics and biomedical research. PET is most effectively used in the study of biochemical processes that

Magnetic resonance imaging (MRI ) (also known as NMR spectroscopy) is based on computer mapping of the response of magnetic fields to short-term application of radio waves. MRI is informative for studying the structure and function of

Electrophysiological methods earlier than others began to be used to indirectly determine the intensity of energy metabolism. We will name two methods that are related to energy metabolism. This is a polarographic method by which the oxygen

The main source of bioelectric processes in the body are cell membranes. The idea of ​​cell membranes as generators of electrical reactions appeared at the beginning of the twentieth and has since developed into a universally recognized scientific

A similar mechanism for the appearance of a potential difference is also observed in the case when solutions of different concentrations with unequal mobility of anions and cations are separated in any way that complicates

SCP is one of the oldest, if not “ancient” electrophysiological indicators. As early as 1827, L. Nobile described the so-called “frog current”, which spread from the limbs to the head. In humans, the direction of such currents

According to experimental data obtained on animals, the surface of the cortex is positively charged (1.5 – 20 mV) with respect to the electrically indifferent points, for which skull bones were most often chosen . In adult rats, the SCP
