Infralow Frequency (ILF) neurofeedback trains the slowest brain frequencies generated in the astrocyte cells of the brain. These slow rhythms are believed to underpin all higher frequency activity of the brain and, as such, determine the overall level of arousal and stability in the central nervous system. Early in the ILF training process, an optimal training frequency is established. The brain’s activity in reference to this frequency is mirrored to the brain through visual, auditory, and tactile feedback. The brain then uses this information to organize itself and its ability to shift from state to state with stability and calm. Benefits are specific to the training, which is guided by protocols that have been developed and refined over the last 30 years. Clients usually notice improvements within the first few sessions, though as with any form of neurofeedback, repetition is required for the gains to be maintained.
