Abstract
The brain which is composed of more than 100 billion nerve cells is a sophisticated biochemical factory. For many years, neurologists, psychotherapists, researchers, and other health care professionals have studied the human brain. With the development of computer and information technology, it makes brain complex spectrum analysis to be possible and opens a highlight field for the study of brain science. In the present work, observation and exploring study of the activities of brain under brainwave music stimulus are systemically made by experimental and spectrum analysis technology. From our results, the power of the 10.5Hz brainwave appears in the experimental figures, it was proved that upper alpha band is entrained under the special brainwave music. According to the Mozart effect and the analysis of improving memory performance, the results confirm that upper alpha band is indeed related to the improvement of learning efficiency.
Highlights
The Cerebral Cortex directs the brain's higher cognitive and emotional functions
The number of times the peak appears in one second is named “frequency”.To some degree, these frequency bands are a matter of nomenclature, but these designations arose because rhythmic activity within a certain frequency range was noted to have a certain distribution over the scalp or a certain biological significance
Brainwave Entrainment refers to the brain's electrical response to rhythmic sensory stimulation, such as pulses of sound or light
Summary
The brain which is composed of more than 100 billion nerve cells is a sophisticated biochemical factory.For many years, neurologists, psychotherapists, researchers, and other health care professionals have studied the human brain They had long believed that brain activity such as brain waves and secretion of brain chemicals were beyond conscious control. Using electrodes adhered to a person's scalp in conjunction with associated electronics (amplifiers, filters, etc.), an electroencephalogram (“EEG”) is recorded over a given time period depicting the electrical activity of the brain at the various electrode sites. The Cerebral Cortex directs the brain's higher cognitive and emotional functions It is divided into two almost symmetrical halves called the cerebral hemispheres. Areas within these lobes oversee all forms of conscious experience, including perception, emotion, thought, and planning, as well as many unconscious cognitive and emotional processes. There are five categories of these brainwaves, ranging from the least activity to the most activity: delta (0 - 4 Hz), theta (4-8 Hz), alpha (8-12 Hz), beta (12-25 Hz) and gamma (25- 100Hz).
