A device may receive, from one or more electrodes, information identifying brain activity for a first time period. The device may predict, based on the information identifying the brain activity for the first time period, predicted brain activity for a second time period that is to occur after the first time period. The device may determine, based on the predicted brain activity for the second time period, a brain stimulus for the second time period, wherein the brain stimulus is associated with a frequency and a phase determined based on the predicted brain activity for the second time period. The device may cause the brain stimulus to be applied in accordance with the frequency and the phase during the second time period.
