记录了平菇（Pleurotus djamor）子实体的胞外电位。我们证明了真菌产生动作电位就像电势的脉冲。观察到尖峰的序列。发现了两种类型的尖峰活动：高频（周期2.6分钟）和低频（周期14分钟）；说明了尖峰模式之间的转换。详细分析了果体在明火短（5秒）和长（60秒）热刺激下的电响应。结果表明，未受刺激的果体对热刺激的反应速度比受刺激的果体快，并具有单个动作电位。
We recorded extra-cellular electrical potential of fruit bodies of oyster fungi Pleurotus djamor. We demonstrated that the fungi generate action potential like impulses of electrical potential. Trains of the spikes are observed. Two types of spiking activity are uncovered: high-frequency (period 2.6 min) and low-frequency (period 14 min); transitions between modes of spiking are illustrated. An electrical response of fruit bodies to short (5 sec) and long (60 sec) thermal stimulation with open flame is analysed in details. We show that non-stimulated fruit bodies of a cluster react to the thermal stimulation, with a single action-potential like spike, faster than the stimulated fruit body does.
