Consciousness and brain

Abstract

After rapid development of science and technology, consciousness has been the subject of intense research in psychology, neuroscience and quantum mechanics. Neuroscience is the most promising field and has made significant progress in understanding the structure and function of brain. Human brain has 100 billion neurons and 100 trillion constantly changing connections. At the root of all our thoughts, emotions and behaviors is the communication between neurons within our brains. Brain waves are produced by synchronized oscillations of group of neurons communicating with each other in very specific frequencies. Hence, Brain wave is rhythmic neural activity in the brain. Brain waves are classified in five bands – delta, theta, alpha, beta, gamma – with different frequencies. The article clearly explains and concludes that consciousness is a function of the brain wave frequencies in these bands.
