The study “Vibrational Trembling Chaos EEG” shows infrasound from devices like the CHI Palm alters brain activity, impacting neural oscillations and neuromodulatory systems.  It compares the Infratonic QGM 3.0 with the Infratonic QGM 4.0 (Chaos model), infrasound devices with differing amounts of signal uncertainty. The infrasound device delivering more Chaos or signal variability was far more effective at inducing enhanced alpha activity throughout the brain. This study advances neuromodulation research, offering insights into the role of signal uncertainty in calming noise in the nervous system and inducing coherent alpha activity in the nervous system for mental clarity, reduced anxiety, shift from sympathic to parasympathetic nervous system activity, and accelerated healing. identifying potential for new infrasound-based therapies.
