Description: Researchers measure the EEG (brain waves) after stunning to determine the electrical current required to render sheep instantaneously insensible. The small plastic devices in the head are for measuring changes in neuro transmitters after stunning. Either electrical or chemical measurements in the brain are the best methods for determining the efficacy of new stunning methods.
