Theta 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 "theta" comes from the Greek letter θ (theta), which is used in mathematics and science to represent a specific type of wave. The term "wave" refers to the pattern of electrical activity that these brain waves produce, which resembles the waves of the ocean.
Function
Theta waves are thought to play a role in sleep, dreaming, and hypnosis. They are also associated with creativity, intuition, and emotional experiences. Some research suggests that theta waves may also be involved in memory consolidation and learning.
Measurement
Theta waves can be measured using an electroencephalogram (EEG), a non-invasive procedure that records electrical activity in the brain. During an EEG, electrodes are placed on the scalp to detect and record brain wave patterns.
Related Terms
- Alpha waves: These are slower brain waves that occur in the frequency range of 8–12 Hz. They are associated with relaxed, wakeful states.
- Beta waves: These are faster brain waves that occur in the frequency range of 12–30 Hz. They are associated with active, alert states.
- Delta waves: These are the slowest brain waves, occurring in the frequency range of 0.5–4 Hz. They are associated with deep, dreamless sleep.
- Gamma waves: These are the fastest brain waves, occurring in the frequency range of 30–100 Hz. They are associated with high-level cognitive processing and problem-solving.
