One way of observing neural activity that happens below our conscience awareness is through EEG (electroencephalogram) which is the measurement of the electrical activity produced when neurons are firing and recharging. Using specialized equipment we measure the EEG at different parts of the brain. The raw signal from these readings can be broken down to show the strength of various frequencies. That information in combination with what a person reports about their day-to-day experiences can be used to make decisions about what adjustments need to be made for the brain to operate more optimally.
