文摘
Glutamate uptake block evokes hypoglossal motoneuron damage due to excitotoxicity. Reactive oxygen species are the earliest excitotoxic players for oxidative damage. Mitochondrial energy deficit is manifested later. Intrinsic cholinergic transmission is inadequate to arrest these events. Nicotinic receptor activation by nicotine provides strong neuroprotection.
