| Lau hypothesizes that ingestion of the well-established neurotoxicants aspartic acid and L-glutamic acid as additives could lead to a high enough body burden to kill neurons by a mechanism called excitotoxicity. Dubner and Ruda (53) suggested that, in the event of prolonged hyperexcitability and hyperalgesia, a pathological state may develop involving excitotoxicity, cellular dysfunction, and loss of descending control mechanisms. Viral-induced spinal motor neuron death is non-cellautonomous and involves glutamate excitotoxicity. |
