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.

我们鉴定了大鼠海马CA1区域中锥体细胞的周围神经元细胞（PNG）。伴随PNG的锥体细胞的最大发射频率明显小于没有PNG的锥体细胞。 PNG的直接去极化增加了锥体细胞的作用电位的发射频率，尤其是在去极化的初始阶段。这些结果表明，PNG构成和活性依赖性地调节了锥体细胞的活性。
