Systems and methods for analyzing brain activity and applications thereof

A method, comprising:

• continuously obtaining, by a specifically programmed computer processor, a recording of electrical signal data representative of an individual's brain electrical activity;
• wherein the recording the electrical signal data representative of individual's brain electrical activity is received from an apparatus configured to be worn on an individual's head, and record:
• i. the individual's brain electrical activity,
• ii. at least one physiological parameter of the individual, selected from the group consisting of:
• heart rate, blood oxygen levels, body temperature, respiration rate, skin temperature, skin conductivity, and movement, and
• iii. at least one environmental parameter;
• continuously projecting, in real time, by the specifically programmed computer processor, the obtained recording of electrical signal data onto a pre-determined ordering of a denoised optimal set wavelet packet atoms, to obtain a particular set of projections of the individual;
• continuously normalizing, in real time, by the specifically programmed computer processor, the particular set of projections of the individual using a pre-determined set of normalization factors to form a set of normalized projections of the individual;
• continuously determining, in real time, by the specifically programmed computer processor, at least one personalized mental state of the individual by assigning at least one specific brain state to the individual based on applying at least one machine learning algorithm to the set of normalized projections of the individual, wherein the at least one specific brain state is associated with a mental state, a neurological condition, or a combination of the mental state and the neurological condition;
• continuously determining, by the specifically programmed computer processor, a relationship between:
• i) the at least one physiological parameter,
• ii) the at least one environmental parameter, and
• iii) the at least one personalized mental state;
• continuously generating, in real time, by the specifically programmed computer processor, an output, comprising:
• 1) a visual indication, wherein the visual indication is representative of the at least one personalized mental state, and
• 2) a feedback output which is configured to affect, based on the relationship, the at least one personalized mental state of the individual.
