Eavesdropping on the brain at sea: development of a surface-mounted system to detect weak electrophysiological signals from wild animals ...
Despite rapid advances in sensor development and technological miniaturization, it remains challenging to non-invasively record small-amplitude electrophysiological signals from an animal in its natural environment. Many advances in ecophysiology and biologging have arisen through sleep studies, whi...
