Human behavior pattern is mainly dictated by cerebral activities called brain wave. Brain wave carries messages to all parts of the body and controls thought and behavior. Modern neuroscientists have divided brain wave into 4 different frequency sub-bands:δ (Delta)、θ (Theta)、α (Alpha)、and β (Beta) in order of frequency. Each sub-band has its own special physiological meaning and characteristic. This research from the perspective of cognitive neuroscience investigates how listening to different styles of music can influence learners ’learning activity. The experiment is conducted by having the subjects listening to different styles of piano music while performing logical reasoning at the same time. In addition, during the experiment, the variation of subject’s brain wave characteristic band with respect to different styles of music is recorded and analyzed. A learning brain wave energy formula is developed to compare the effects of different styles of music to the learning. The research result shows some specific styles of music have a positive effect in enhancing learning energy and improve learners learning efficiency.

In the era of wireless communication, WiFi becomes an indispensable accessory to most of us. People use WIFI to interact with the wireless Internet, perform commercial and financial transactions, or conducting recreational activities, etc.Though it offers a more convenient life to people, the strong Electromagnetic waves(EMW) resulted from it endangers human health, that has already turned out to be the primary study for medical science. Furthermore, EMW also attracts concern and panic of the inhabitants living in the surroundings which is filled with high-frequency and low-frequency EMwave. EMW today comes from broadcast towers, the system of the wireless communication, GPS, TVs and defense satellites mostly. Enjoying the convenience resulted from communication technology, people nowadays should also concern about whether EM wave would damage people’s health at the same time. Based on the perspective of cognitive neuroscience, this study mainly focuses on how EM wave produced from WiFi affects subject’s brainwaves under a specific physiological situation. The researcher observes different changing of brainwave when human beings expose in various strength of EM wave, and analyses the affection of EMW toward subject’s brainwaves.
