"'Within the Air Force, various operations such as remotely piloted and manned aircraft operations require a human operator to monitor and respond to multiple events simultaneously over a long period of time,' researchers at Wright-Patterson Air Force Base in Ohio wrote in the journal Frontiers in Human Neuroscience.
'With the monotonous nature of these tasks, the operator's performance may decline shortly after their work shift commences.'
Brain stimulation kits use five electrodes to send weak electric currents through the skull and into specific parts of the cortex."
