Clinical EEG and Neuroscience, 2008
A prominent theta rhythm dominates the EEG of rodents such as rabbits, rats and mice. This rhythmical activity is preponderant in the hippocampus and may become quite widespread; it is usually arousal-related and generated by cholinergic mechanisms. This pattern has been intensively studied by experimental neuroscientists but is rather little known in

Clinical Electroencephalography, 1994
The theta rhythm that appears in the frontal midline was studied morphologically and clinically in EEGs performed on 788 patients and 161 normal subjects in their late teens or older. This theta rhythm was classified into 2 types. The Type 1 theta rhythm appeared in short bursts maximally in the Fz lead and spread mainly to the anterior region.

Differential shaping of EEG theta rhythms
Biofeedback and Self-Regulation, 1976Heart rate, EEG, frontal EMG, and forearm EMG were recorded in 20 subjects for 3 baseline, 8 feedback, and 2 postbaseline sessions in order to compare two biofeedback methods of teaching subjects to increase theta EEG activity. Subjects were divided into high- and low-EMG groups.

Video Game-Induced Theta Rhythm
Journal of Clinical Neurophysiology, 2019Summary: Smartphones and other personal electronic devices present novel cortical processing tasks with potential for identification of novel EEG waveforms. A 17-year-old patient with epilepsy manifested as recurrent myoclonic seizures, absence seizures, and a single generalized tonic–clonic seizure was hospitalized to undergo video-EEG ...

Frontal midline theta rhythm and mental activity
Psychiatry and Clinical Neurosciences, 1998Theta rhythm at the midline of the frontal area can be observed in normal subjects, during mental task performance, rest and sleep. Frontal midline theta rhythm (Fm theta) is a train of rhythmic waves at the frequency of 6- Hz and can be induced by various mental tasks. Fm theta is induced not only during mental tasks but also during nocturnal sleep in

Theta rhythms: State of consciousness
Brain Topography, 1990The role of midline frontal theta in human is discussed, with reference to its relation on consciousness. Clinical observations of the appearance of this theta activity under various conditions are reviewed. These include simulated diving, brain tumour, chemical intoxication, exercise, mental calculation, sleep and medication.

EEG theta rhythm in infants and preschool children
Clinical Neurophysiology, 2006To study behavioral correlates of theta oscillations in infants and preschool children.EEG was recorded during baseline (visual attention) and two test conditions--exploration of toys and attention to 'social' stimulation. Age specific frequency boundaries of theta and mu rhythms were assessed using narrow bin analysis of EEG spectra.Theta spectral ...

Mechanisms and Functions of Theta Rhythms
Annual Review of Neuroscience, 2013The theta rhythm is one of the largest and most sinusoidal activity patterns in the brain. Here I survey progress in the field of theta rhythms research. I present arguments supporting the hypothesis that theta rhythms emerge owing to intrinsic cellular properties yet can be entrained by several theta oscillators throughout the brain.

Theta Rhythm in Hippocampus and Cognition
2020Theta rhythm is a large 4–12 Hz oscillatory activity that is predominant during wake and REM (rapid eye movement) sleep in the hippocampus. Theta rhythm is generated by the interplay between neurons from the medial septum and entorhinal cortex, with local oscillators within the hippocampus.

Does a Healing Procedure Referring to Theta Rhythms Also Generate Theta Rhythms in the Brain?
The Journal of Alternative and Complementary Medicine, 2016ThetaHealing® (Vianna Stibal, Kalispell, MT) is a spiritual healing method in which the practitioner and client engage in joint meditations during several healing sessions. It is claimed that these meditation periods are characterized by a "theta state" in which the presence of theta-waves in the electroencephalograph (EEG) frequency spectrum of both ...
