Excitotoxicity is a primary pathological process directing neuronal cell death in both acute neurological disorders and neurodegenerative diseases such as ischemic stroke and Alzheimer’s disease. We use mouse cultured cortical neuron treated with 100uM of Glutamate for a model of excitotoxicity and applied N-terminomics (TAILS) method to identify the neuronal proteins aberrantly modified in excitotoxicity
