Which frequency range is typically observed in theta waves during an EEG?

Theta waves are characterized by their frequency range, which is typically observed between 4 to 8 Hz in an electroencephalogram (EEG). These waves are associated with various states of consciousness, such as light sleep, relaxation, and creativity, as well as periods when the brain is processing information or transitioning between sleep and wakefulness. This frequency range is significant in the context of brain activity because it reflects particular cognitive and emotional states, making it essential for both clinical assessments and understanding normal brain function. The specific definition of theta waves aligns well with this frequency range, highlighting their role in EEG interpretations within a clinical environment.
