Complex cognitive tasks such as mental arithmetic heavily rely on intact, well-coordinated prefrontal cortex (PFC) function. Converging evidence suggests that frontal midline theta (FMT) oscillations play an important role during the execution of such PFC-dependent tasks. Additionally, it is well-established that acute stress impairs PFC function, and recent evidence suggests that FMT is decrea...

This article examines the economic effects of all forms of stress-work-related stress, home stress, and post-traumatic stress disorder (PTSD)-as health hazards. Such an approach inherently broadens the analysis from a few well-defined, quantitative variables, such as those most commonly studied by economists who traditionally examine job stress alone. It also enables us to draw conclusions rega...

The concept of neural efficiency provides a powerful framework to assess the underlying mechanisms of brain dynamics during cognitive-motor performance. Electroencephalography (EEG) studies have revealed that as cognitive-motor performance improves non-essential brain processes are progressively disengaged resulting in brain dynamics leading to a state of neural efficiency. Multiple factors suc...
