Table 1 Experimental measurement-based quantification results of three neurotransmitter mixture cases with and without ascorbic acid (1 mM of vitamin C): (Case I) 0.035, 0.010 and 0.005 mM; (Case II) 0.39, 1.11, and 0.68 mM; and (Case III) 1.10, 3.24, and 2.37 mM of L-tyrosine, L-dopa and dopamine, respectively
