Beta waves (== Template:IPA ==
The Template:IPA (International Phonetic Alphabet) is a system of phonetic notation based primarily on the Latin alphabet. It was devised by the International Phonetic Association in the late 19th century as a standardized representation of the sounds of spoken language.
Pronunciation
The pronunciation of the term "IPA" is /aɪ piː eɪ/ in English.
Etymology
The term "IPA" is an acronym for the International Phonetic Alphabet. The International Phonetic Association, founded in 1886, created the IPA to provide a single, universal system for the transcription of spoken language.
Related Terms
- Phonetic notation: A system used to visually represent the sounds of speech. The IPA is one type of phonetic notation.
- Phonetics: The study of the physical sounds of human speech. It is concerned with the physical properties of speech sounds (phonemes), and the processes of their physiological production, auditory reception, and neurophysiological perception.
- Phonology: The study of the way sounds function within a particular language or languages. While phonetics concerns the physical production, acoustic transmission and perception of the sounds of speech, phonology describes the way sounds function within a particular language or languages.
- Transcription (linguistics): The systematic representation of spoken language in written form. The source of the words transcribe and transcription, the term means "to write across" in Latin, and it's the process of converting spoken language into written form. In linguistics, this is often done using the IPA.

Etymology
The term "Beta wave" was coined in the early 20th century, deriving from the second letter of the Greek alphabet, beta (β). This was due to the fact that these waves were the second type of brain wave to be discovered, following the alpha waves.
Function
Beta waves are present in the brain when an individual is awake and alert. They are involved in conscious thought, logical thinking, and tend to have a stimulating affect. When beta wave activity becomes very intense, it is often indicative of stress, anxiety, or restlessness.
Related Terms
- Alpha wave: A type of brain wave that is slower and of higher amplitude than beta waves. They are typically associated with relaxation and calmness.
- Theta wave: A type of brain wave that is even slower than alpha waves. They are typically associated with deep relaxation and meditation.
- Delta wave: The slowest type of brain wave, typically associated with deep, dreamless sleep.
- Gamma wave: A type of brain wave that is faster than beta waves. They are typically associated with high-level information processing and insight.

- Neurofeedback: A type of biofeedback that uses real-time displays of brain activity to teach self-regulation of brain function.
