From: Eavesdropping on the brain at sea: development of a surface-mounted system to detect weak electrophysiological signals from wild animals

Fig. 5

Signal quality comparison across several surface-mounted electrodes. This recording demonstrates brain wave attenuation during euthanasia and the superior signal quality of A genuine GRASS® goldcup electrodes; B DATWYLER SoftPulse™ flat dry; C dry brush electrodes; D soft-dry DRYODE™ electrodes. Snap-on surface-mounted electrodes with conductive gel and adhesive reliably detected E muscle activity (EMG) and F heart rate (ECG) attenuation. (Note, the veterinarian-ordered euthanasia was related to congenital defects and unrelated to this study.)
