  2. Theta wave - Wikipedia

    en.wikipedia.org/wiki/Theta_wave

    Hippocampal theta waves, with a frequency range of 6–10 Hz, appear when a rat is engaged in active motor behavior such as walking or exploratory sniffing, and also during REM sleep. [3] Theta waves with a lower frequency range, usually around 6–7 Hz, are sometimes observed when a rat is motionless but alert.

  3. Electroencephalography - Wikipedia

    Theta waves. Theta is the frequency range from 4 Hz to 7 Hz. Theta is seen normally in young children. It may be seen in drowsiness or arousal in older children and adults; it can also be seen in meditation. [86] Excess theta for age represents abnormal activity.

  4. High-frequency oscillations - Wikipedia

    en.wikipedia.org/wiki/High-frequency_oscillations

    Traditional classification of the frequency bands, that are associated to different functions/states of the brain and consist of delta, theta, alpha, beta and gamma bands. . Due to the limited capabilities of the early experimental/medical setup to record fast frequencies, for historical reason, all oscillations above 30 Hz were considered as high frequency and were difficult to investigate.

  5. Microsleep - Wikipedia

    Example of an EEG alpha wave Example of an EEG theta wave. A microsleep is a sudden temporary episode of sleep or drowsiness which may last for a few seconds where an individual fails to respond to some arbitrary sensory input and becomes unconscious.

    The exact purpose of its appearance in NREM is not understood. In NREM sleep, thalamocortical oscillatory activity is still present, but the overall frequencies range from the slow (<1 Hz), to the delta (1–4 Hz), and theta (47 Hz) range. [12] Synchronized theta oscillation has additionally been observed in the hippocampus during NREM. [12]

    For example, phase–amplitude coupling is where the phase of a slow wave is coupled with the amplitude of a fast wave. [70] The theta-gamma code is a coupling between theta wave and gamma wave in the hippocampal network. During a theta wave, 4 to 8 non-overlapping neuron ensembles are activated in sequence.
