Abstract
The slow negative potential of the direct cortical response is similar in its shape, time course, and relationship to repetitive stimulation to depolarization of cortical glial cells but differs from the IPSP of cortical neurons. According to the results of digital spectral (frequency) analysis, the basis of the slow negative potential is the glial component formed by summation of components which coincide with glial depolarization processes with an accuracy determined by a constant factor. The much smaller component (as regards relative contribution) is the indirect result of the development of an IPSP in the neurons.
