title: [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].
abstract: 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 potential evoked by stimulation through S was depressed. The depression of the dendritic potential was found to correlate with [K+]0.
