Fig. 3From: Eavesdropping on the brain at sea: development of a surface-mounted system to detect weak electrophysiological signals from wild animalsCustom wire assembly, attachment, and headcap cross-section. A Wiring schematic from electrodes to the 21-pin underwater connector with callouts showing wire shielding and sheathing and the internal structure of the plotted splice joint between electrode and connector wires. B Diagram showing attachment placement and method for each component, including logger, ECG, EMG, and headcap patches. C Headcap cross-section showing internal components of the headcap, including the splice joints within the 3D-printed mold and each successive layer of shielding and sheathing until the outer layer of nylon meshBack to article page
