- Each row indicates the appearance of a peak or valley in the third harmonic difference before and after the stimuli. Rows 1 to 6 correspond to a single measurement before and after the stimuli, whereas rows 7 to 9 correspond to repeated measurements. The second column indicates the material of the electrode. The third and fourth column indicates the frequency and voltage where a maximum was observed. The fifth column indicates the amplitude of that maximum. Gold electrode were polished to 1 μm, and stainless steel (experiments 5 and 6) was polished as indicated in column one. All experiments were performed with inhibitor of the enzyme (SMV), except experiment #9 where glucose was added.
