Abstract: Real time mirroring of dominant brain frequencies through the use of two types of stimuli is provided. Through devices and methods that simultaneously look for asymmetries and in real time, one can create real time variable sequences of acoustic and electric stimuli, and then one can effectively and efficiently support the brain to balance its activity between corresponding right and left lobes without one's mindful attention.

Abstract: Exposure to stressors may be associated with the production of asymmetry in brain waves and can significantly affect a person's overall degree of wellbeing and conversely, asymmetry may influence a person's experience of stress. Through devices and methods that simultaneously look for asymmetries and in real time, one can create real time variable sequences of acoustical stimuli, and then one can effectively and efficiently support the brain to balance its activity between corresponding right and left lobes without one's mindful attention. Additionally various devices and methods can be used to identify condition states, including stress state conditions.

Abstract: A method for affecting balanced brain functioning with relational ambient sound is disclosed. During the process of balancing the brain's activity, an ambient sound is played for the subject to hear. The subject's brain develops a relationship between the process of bringing the brain to a balanced state and the ambient sound. As a result of this relationship, balanced brain functioning may then be affected by exposing the subject to that same ambient sound.
