Research Abstract

We identified perineuronal glial cells (PNG) of pyramidal cells in CA1 region of the rat hippocampus. The maximum firing frequency of the pyramidal cells accompanying the PNG was significantly smaller than that of the pyramidal cells without PNG. Direct depolarization of PNG increased the firing frequency of action potentials of pyramidal cells, especially in the initial phase of the depolarization. These results indicate that the PNG modulate the activity of pyramidal cells constitutively and activity-dependently.
