Threohydroxyaspartate (THA)-induced glutamate excitotoxicity in organotypic culture of rat spinal cord is a well-known model of motor neuron degeneration. THA causes accumulation of synaptic glutamate and over stimulation of the postsynaptic receptor by inhibiting glutamate uptake. This model has also
