Approaches Functional neuroimaging A central goal of neuroergonomics is to study the way in which brain function is related to task/work performance. To do this, noninvasive neuroimaging methods are typically used to record direct neurophysiological markers of brain activity through electrical activity Electroencephalography (EEG), Magnetoencephalography (MEG) or through indirect metabolic Positron-emission tomography (PET) and neurovascular measures of neural activity including Functional magnetic resonance imaging (fMRI), Functional near-infrared spectroscopy (fNIRS), transcranial Doppler (TCD) sonography. Typically, neuroergonomic studies are more application-oriented than basic cognitive neuroscience studies and often require a balance between controlled environments and naturalistic settings. Studies using larger room-scale neuroimaging setups such as PET, MEG, and fMRI, offer increased spatial and temporal resolution at the expense of increased restrictions on participants actions. Using more mobile techniques such as fNIRS and EEG, research may be conducted in more realistic settings including even participation in the actual work being investigated (ex: driving). These techniques have the advantage of being more affordable and versatile, but may also compromise by reducing the number of areas recorded and the ability to image neural activity from deeper brain regions. Together the application of both controlled lab experiments and the translation of findings in realistic contexts represents the spectrum of neuroimaging in neuroergonomics. Neurostimulation Neurostimulation methods may also be used apart, or in conjunction with neuroimaging approaches to probe the involvement of cortical regions in task performance. Techniques such as transcranial magnetic stimulation (TMS) and Transcranial direct-current stimulation (tDCS) can be used to temporarily alter the excitability of cortical regions. It is proposed that stimulating a cortical region (particularly with TMS) can disrupt or enhance that regions function, permitting researchers to test specific hypotheses related to human performance. Some studies have shown the promise of using transcranial magnetic stimulation (TMS ) and transcranial direct-current stimulation (tDCS ) to improve cognitive skills during tasks. While initially used to treat various neurological disorders such as Parkinson's disease or dementia, the scope of TMS is expanding. In TMS, electricity is passed through a magnetic coil that is positioned near the person's scalp. Results from studies show that noninvasive brain stimulation leads to 20 more minutes of sustained vigilance performance.R. Andy, M., Nathaniel, B., Craig M., W., & Jeremy, N. (n.d). Modulating the brain at work using noninvasive transcranial stimulation. NeuroImage, 59(Neuroergonomics: The human brain in action and at work), 129-137. Psychophysiology Psychophysiological measures are physiological measures (blood, heart rate, skin conductance, etc.) which change as part of psychological processes. Although not considered as a direct neural measure, neuroergonomics also promotes the use of physiological correlates as dependent measures when they can serve as an index of neural activities such as attention, motor, or affective processes. These measures can be used in conjunction with neuroimaging measures, or as a substitute when the acquisition of neuroimaging measures is too costly, dangerous, or otherwise impractical. Psychophysiology is a distinct field from neuroergonomics , however the principals and objectives can be considered complementary. Results of evaluation pointed to the VRS an “ excellent learning tool ” for increasing a student's knowledge on the procedure. All eight of the nursing faculty who participated agreed to this much, and that they would recommend that students work with the VRS before performing the IV catheter insertion on real patients.
