Different electrode montages used by the six technical setups. Electrode labels follow from the human 10–20 system, where letters indicate the lobe - Fp=pre-frontal, F=frontal, P=parietal, T=temporal, and C=center. The left and right zygomatic arch are also depicted as LZA and RZA. Odd numbers refer to electrode placement on the left side and even numbers indicate placement on the right side of the brain. Reference electrode positions are highlighted in orange. It is worth pointing out that large variance amongst canine breeds means the figure is not representative of all canine individuals
