The actions of neurotransmitters involved in the sleep-wakefulness cycle on neurons located in the ventral part of the oral pontine tegmentum were studied in a rat brain-slice preparation. Results show that glutamate and histamine evoke depolarizations and spike firing while serotonin and gamma-aminobutyric acid evoke hyperpolarizations. The excitatory and inhibitory actions of these neurotransmitters increase pontine neuron activity during the conditions occurring during paradoxical sleep.
在大鼠脑片制备中,研究了参与睡眠 - 觉醒周期的神经递质对位于脑桥被盖腹侧部神经元的作用。结果表明,谷氨酸和组胺可引起去极化和动作电位发放,而血清素和γ-氨基丁酸则引起超极化。在异相睡眠期间出现的条件下,这些神经递质的兴奋和抑制作用会增加脑桥神经元的活动。
