[Changes in the concentration of intracellular potassium and the phenomenon of dendritic potential depression against a slow negative potential background in the cat cerebral cortex]

Autor: A I, Roĭtbak, I V, Ocherashvili

Publikováno v: Neirofiziologiia = Neurophysiology. 15(2)

Two stimulating electrodes (S1 and S2), a recording macroelectrode and a K+-selective microelectrode were placed on g. suprasylvius of cat. A stimulus applied through S1 elicited slow negativity and an increase in [K+]0. At this time the dendritic po

[Glial origin of negative shifts in the surface potential of the brain upon tetanic stimulation: microelectrode study and mathematical analysis]

It is shown in experiments on anesthetized cats that negative shift of the cortical surface potential evoked by its tetanic stimulation is similar in form and time course to the depolarization of glial cells. On the contrary, hyperpolarizing shifts o

[Glial origin of the slow negative potential of the direct cortical response: microelectrode study and mathematical analysis]

Autor: A I, Roĭtbak, V V, Fanardzhian, D S, Melkonian, A A, Melkonian

Publikováno v: Neirofiziologiia = Neurophysiology. 14(1)

Slow negative potential of a direct cortical response is similar in configuration, time-course and reaction to repeated stimuli to depolarization of the cortical glial cells and differs from IPSP of the cortical neurons. According to data of digital

[Changes in the concentration of extracellular potassium and the slow negative potential in the somatosensory area of the cortex in response to stimulation of the ventroposterolateral nucleus of the thalamus in the cat]

Autor: I V, Ocherashvili, A I, Roĭtbak, A V, Bobrov, R G, Kapel'

Publikováno v: Neirofiziologiia = Neurophysiology. 15(2)

A single electrical stimulus applied to the VPL nucleus with intensity, strong enough to elicit in gyrus sigmoideus posterior slow negativity following the primary response, caused a local increase in [K+]0 reaching 0.2 mM. On the basis of this findi
