概括

异氨酸麻醉会增加Na_v1.6通道,导致大脑网络活动异常和认知能力下降. 利多卡因可以预防这些影响,为手术前神经认知障碍 (PND) 提供潜在的治疗方法.

科学领域:

神经科学是一个神经科学.
麻醉学麻醉学
药理学药理学是指药理学的学科.

背景情况:

术后神经认知障碍 (PND) 是麻醉的严重并发症,导致患者的治疗结果差,医疗费用增加.
异黄素诱导的PND背后的机制尚未完全理解,尽管涉及电压通道 (VGSCs或Na_v).

研究的目的:

调查Na_v1.6亚型在异黄素诱导的PND中的作用.
探索针对Na_v1.6进行治疗干预的潜力.

主要方法:

检查海马Na_v1.6表达和电脑电图 (EEG) 活动在暴露于异黄的小鼠中.
在用利多卡因调节Na_v1.6后评估谷氨酸释放和认知功能.

主要成果:

暴露于异氨酸会增加海马体Na_v1.6的表达,导致神经网络刺激性异常 (β和γ频段EEG功率降低) 和过度的谷氨酸释放.
利多卡因的使用降低了Na_v1.6的调节,缓解了网络过度兴奋,减少了谷氨酸释放,并改善了暴露于异氨酸的小鼠的认知表现.

结论:

异氨酸诱导的PND可能源于Na_v1.6的表达增加,导致网络干扰和兴奋毒性.
利多卡因作为一种治疗剂,可以通过向Na_v1.6.6来预防或治疗因异黄素引起的认知障碍.

Antiepileptic Drugs: Sodium Channel Blockers

Antiepileptic Drugs: Sodium Channel Blockers

Antiepileptic drugs are specialized medications that prevent seizures in individuals diagnosed with epilepsy. These drugs primarily function by blocking the movement of sodium ions through channels in the neuronal membrane, inhibiting the repetitive firing of action potentials often associated with seizures.
Sodium channel blockers modulate ion channels, particularly voltage-gated sodium channels. They block only sodium ion movement.
Among the most commonly prescribed antiepileptic drugs are...

Modulating Cognition Using Transcranial Direct Current Stimulation of the Cerebellum

Transcranial direct current stimulation (tDCS) over the cerebellum exerts a remote effect on the prefrontal cortex, which can modulate cognition and performance. This was demonstrated using two information-processing tasks of varying complexity, whereby only cathodal tDCS improved performance when the task was difficult, but not...
