Abstract: A method for ameliorating an insomnia of a user having a brain wave includes steps of defining a specific frequency range of 8 to 12 Hz as a ? rhythm in the brain wave, detecting a total power under the specific frequency as a ? rhythm intensity of the user, providing one of an animation and a wave form representative of the ? rhythm intensity of the user, and inducing the ? rhythm of the user by watching one of the animation and the wave form by the user.

Abstract: A neurofeedback training device and a method thereof are provided. The neurofeedback training device includes a processor, a monitor and a mu rhythm training interface. The processor receives and processes a signal relevant to a mu rhythm. The monitor is electronically connected to the processor, and the mu rhythm training interface is displayed on the monitor.

Abstract: An apparatus and a method of enhancing at least one of memory ability and parasympathetic activity of a subject are provided. The apparatus includes a training element for increasing a mu rhythm of the subject, and the method includes a step of increasing the mu rhythm of the subject.
