... NOTE: The points in this list were made by the individual speakers identified above; they are not intended to reflect a consensus among workshop participants. The effects of non-invasive brain stimulation technologies on cognition and performance has both therapeutic and non-therapeutic applications, depending on whether they are used to ameliorate symptoms of a disorder or enhance otherwise normal function.

... They had not only improved reaction time in comparison to those who received the sham stimulation, but also decreased salivary cortisol concentrations, indicating lower stress. Interestingly, however, when the same stimulation protocol was used in individuals who did not have math anxiety, reaction time increased compared to sham stimulation and cortisol levels increased (Sarkar et al., 2014)

... The study in 96 healthy subjects showed that tDCS stimulation resulted in significant improvements in learning and performance, and that these improvements were sustained after training. Another study designed to investigate the perception of fatigue on performance in elite cyclists showed that tDCS stimulation of the temporal cortex delivered prior to an incremental maximal cycling test resulted in a reduction in heart rate as power increased, and a 4 percent improvement in performance (Okano et al., 2013)

... Daniel Wetmore, director of intellectual property and usability at Thync, described their device as a wearable Bluetooth® technology controlled unit that snaps into electrodes worn on the temple area of the head with a second electrode either behind the ear or on the back of the neck to deliver electrical stimulation. The company claims its device can modulate psychophysiological arousal by delivering pulsed neurostimulation waveforms (called "Vibes")
