Large networks in the brain influence each other by using waves of electricity in slow rhythms. These oscillating signals are measured in fractions of a cycle per second, with the optimal rhythms being 1 cycle every 10 seconds. To put this into perspective the lowest sound that is audible to the human ear is 20 cycles a second. Even through these rhythms are slow, they are the fastest processes to make neuroplastic change. Making and breaking synapses takes minutes to hours, but changing these network influences only takes a matter of seconds. While these network rhythms cause rapid change in brain function, they also make it harder for the brain to re-establish old patterns. Capturing these rhythms and restoring them to normal is an excellent strategy for restoring normal brain processes and function.
