The relationship between the functional activity of the brain, energy supply, pH and blood flow

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

Electrophysiological methods for determining energy metabolism

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

History of the study of the level of constant potential of the brain

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

Analysis of the origin of SCP when registering electrical activity from the brain

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
