The effect of thyrotropin-releasing hormone (TRH) was studied in 30 hypoglossal motoneurons from brainstem slices of guinea pigs. Bath application of TRH resulted in an increase of the spontaneous excitatory synaptic activity, depolarization of the neurons, increase of the input resistance and change of the duration of the falling phase of excitatory postsynaptic potentials. The depolarizing response and membrane conductance change was the result of a direct postsynaptic action of TRH, possibly mediated by a reduction of a potassium conductance.
在豚鼠脑干切片的30个舌下运动神经元中研究了促甲状腺激素释放激素（TRH）的作用。浴槽中应用TRH导致自发兴奋性突触活动增加、神经元去极化、输入电阻增加以及兴奋性突触后电位下降相持续时间改变。去极化反应和膜电导变化是TRH直接突触后作用的结果，可能是由钾电导降低介导的。
