Figure 2: NMI results from resected epileptogenic tissue of hippocampal pyramidal layer (Gray matter) in early neurodegeneration: Monoamines: Dopamine (DA), Serotonin (5-HT). On the x-axis: oxidation potential in term of applied voltage in volts (V). On the y-axis: current in picoamperes (pA). Note that the x-axis terminates at approximately 0.45V due to the low detection limit of L-tryptophan and neuropeptides in early neurodegeneration.
