Disclosed is a method, apparatus and neuro-feedback system for processing neuro-signals of a user's brain to derive mean brain frequency that correspond to a homeostasis condition of the user's Autonomic Nervous System (ANS). The derived mean brain frequency from the neuro-signals or bio signals of the user's brain correspond to Brain Frequency Variability (BFV) index that also correspond to a homeostasis condition of the user's ANS like the mean brain frequency. The disclosed system can be used to train the user's brain using one or more guided interventions in response to the derived mean brain frequency or the BFV index to correct thoughts, perceptions, and stimuli that influences state of the user's neuro-signals.
Deriving mean brain frequency as a measure of homeostasis and providing guided interventions to correct thoughts,perceptions,and stimuli effecting the user's neuro signals
