Abstract: To alleviate information-dependent behavior by using a mobile terminal of a user of the mobile terminal. A mobile terminal including a first signal generator that generates a frequency signal in the audible band, a second signal generator that generates a high-frequency signal in a frequency band higher than the audible band, a speaker that converts the high-frequency signal into a corresponding high-frequency sound, and a timing controller that controls timing of the generation of the high-frequency signal to be a timing that does not correlate with the timing of the generation of the frequency signal in the audible band is provided.

Abstract: A space is set substantially in a tropical rain forest type environment to activate a human's essential brain region and realize an environment suitable for the human's brain by arranging a device for setting the tropical rain forest type environment based on characteristics of activating human's essential brain region responsive to tropical rain forest type environment information, in a space such as an urban space, a housing space or other living space. The tropical rain forest type environmental information has higher density and higher complexity than those of urban space type environmental information, and includes at least one of auditory information, visual information, and super perceptual information of aerial vibration. The tropical rain forest type environmental information is comfortable for the human with no excessive stress, and is environmental information for effecting prevention and treatment of diseases due to stress by realizing the environment comfortable for the human's brain.

Abstract: A means is provided for generating a vibration or a vibration signal, which contains audible range components that are vibration components in the audible frequency range and super-high-frequency components within a range exceeding the audible frequency range up to a predetermined maximum frequency, and which has an autocorrelation order represented by at least either one of a first property and a second property. By applying the vibration or an actual vibration generated from the vibration signal to a human being, a fundamental brain activation effect activating the fundamental brain network system constituted of a fundamental brain including the brain stem, thalamus and hypothalamus that are regions to bear the fundamental function of the human being and the fundamental brain network of neuronal projection from the fundamental brain to various brain regions is introduced.
