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 ...

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.

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 ...

Theta rhythm: The brain stem involvement
Neuroscience & Biobehavioral Reviews, 1992This review considers the influence of brain stem transections on hippocampal theta rhythm appearance in the acute transected rat and cat. The pretrigeminal transection induces in both species continuous or almost continuous low-frequency theta rhythm while the cortex is desynchronized.

A circadian rhythm of hippocampal theta activity in the mouse
Physiology & Behavior, 1985Hippocampal theta activity dominates the cortical EEG of the mouse during certain behaviors. We have therefore been able to study the circadian distribution of hippocampal theta activity by means of chronic EEG implantation and computerized EEG state scoring.

Episodic Rage, Theta Rhythm, and Obsessions
Journal of Mental Science, 1953The association of an abnormal electroencephalogram with obsessive-compulsive states has been investigated by Pacellaet al.(1944), who found in these states a higher incidence of “convulsive-type” patterns, consisting of occasional or frequent runs of serial 2–4 c/s potentials of high amplitude than in a random control group.
