Using the NeuroPace RNS system to monitor long-term epileptic-like activity, researchers have confirmed that there is a uniform circadian pattern to this brain activity. Studying 134 subjects, Spencer et al found the epileptiform activity peaked during normal sleeping hours. They also discovered a monophasic, nocturnally dominant rhythm in the neocortical areas of the brain and a more complex pattern, with a diurnal peak, in limbic sections of the brain. Some volunteers were also found to have a dual oscillator pattern to the brain activity, displaying a circadian and ultradian pattern.
