The visual unit is used to complete the phenomenon of AVE. This utilizes the binaural beats discussed in the audio unit as well as visual stimuli produced in the visual unit. AVE, a subset of brainwave entrainment, uses flashes of lights and pulses of tones to guide the brain into various states of brainwave activity. AVE devices are often termed light and sound machines or mind machines. Altering brainwave activity is believed to aid in the treatment of psychological and physiological disorders.
Dimensions of Ethical Direct-to-Consumer Neurotechnologies
Published in AJOB Neuroscience, 2019
There are currently a number of EEG sensor headsets on the market intended for consumers to improve their brain functioning. The Neurosky Mindwave (Neurosky 2018a), for example, can be paired with a plethora of third-party brainwave entrainment applications to, purportedly, increase focus and attention, reduce stress and anxiety, enhance cognition, increase motivation, strengthen emotional stability and mental health, and improve creativity (Neurosky 2018b). However, many of these claims do not hold up to scrutiny. Positive findings cited in support of the technology are often overstated or at least not expressed with appropriate nuance. A study that is frequently cited to support the claim that EEG headset brain entrainment can boost creativity (Fink, Schwab, and Papousek 2011) does not examine EEG brain entrainment at all. Rather, it finds a correlation between creative idea generation and alpha synchronization activity. In fact, while this study showed that affective and cognitive stimuli could enhance alpha activity, the stimuli did not enhance the originality of ideas that were created (Fink, Schwab, and Papousek 2011). It is misleading to use such studies as evidence for the claim that EEG entrainment can improve an individual’s ‘creativity’. To the lay person, ‘creativity’ entails ‘originality’, not simply alpha wave activity. To represent it differently flouts the principle of honesty and violates a user’s right to autonomous decision making.

It is worth mentioning that the binaural beat frequency of 7 Hz (theta frequency range) was able to decrease anxiety, stress, and consequently reduce motion artifact in patients undergoing MPI in this study. The initial frequency of 15 Hz (beta frequency range) during the first 3 min of the audio file was set to tune with pre-imaging anxiety in which the brainwave pattern was likely to be a beta pattern or arousal state. So, through brainwave entrainment, a 7 Hz binaural beat would induce the brain to produce a 7 Hz beat corresponding to a relaxed state or theta pattern [21].
