External stimuli are converted into electrical signals by sensory organs and dynamically processed by neural circuits in the brain. Brain waves reflect this neural activity, with differences in time constants between regions manifesting as differences in frequency. Brain waves interact with external stimuli and other regions of the brain, and are responsible for the hierarchical and integrative processing of sensory information. In vision, gamma waves are involved in bottom-up processing, while beta waves are involved in top-down processing. In hearing, EEG synchronization with the audio envelope influences comprehension. EEG phase synchronization is also related to musical preferences, and future developments in brain-machine interface technology utilizing EEG are anticipated.
