Depression is the leading cause of disability worldwide. Even before the events of 2020, depression has been on rise since over the last several decades. Scientific investigation into the depths of psychology and neuroscience have illuminated some characteristic structural and functional features of depression. This means that a brain whose behavior produces the state of depression, is doing something different by virtue of its chemical and electrical activity, and has a different physical structure. These differences are both measurable and reliable. The electrical way of measuring brain activity has been used in clinical and medical settings for over 70 years. Certain electrical brain waves correspond to specific brain and mind states, such as excitement or depression.
It is known that the only reason that the brain perpetuates certain common states is because it is a state that the brain has learned to use in dealing with a certain demand. When any environmental demand is placed on the organism, the brain strategizes to deal with it, in order to ensure its own survival. The reason that the brain sometimes ends up with poor function, is because a strategy it has learned in the past, is either too physiologically taxing, or inappropriate in the current context. This often manifests as depression.
Neurofeedback technology allows the brain to learn new strategies that, over time replaces the old and outdated ones. By simply rewarding the brain with specifically tuned sounds, or visual graphics, the brain learns to perform only those behaviors with which the rewards are associated. Similarly to learning how to ride a bike, which once learned, can be retained over a lifetime. even if decades pass between riding one, the brain learns new strategies which it retains beyond the initial training sessions.
