Neuromodulation, theta rhythm and rat spatial navigation
Neural Networks, 2002Cholinergic and GABAergic innervation of the hippocampus plays an important role in human memory function and rat spatial navigation. Drugs which block acetylcholine receptors or enhance GABA receptor activation cause striking impairments in the encoding of new information.

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

Phasic modulation of hippocampal synaptic plasticity by theta rhythm.
Behavioral Neuroscience, 2020Theta rhythm and long-term potentiation (LTP) are 2 remarkable discoveries. The theta rhythm is an oscillatory neural activity of 3-10 Hz in the hippocampus. LTP is implicated as a cellular basis of memory, but the function of theta oscillation in memory

Voluntary exercise enhances hippocampal theta rhythm and cognition in the rat.
Behavioural Brain Research, 2020Regular exercise promotes learning and memory functions. Theta activity is known to relate to various cognitive functions. An increase in theta power may be related to higher cognitive functioning and learning functions.

Thirty-six patients had a midline theta rhythm in the electroencephalogram that consisted of a train of rhythmic waveforms in the theta frequency range (4 to 7 Hz), which occurred as a focal rhythm in the midline leads and was usually most prominent in the central vertex lead.

Electroencephalography and Clinical Neurophysiology, 1954
Abstract The EEGs of 37 patients are described, in which the only, or major, abnormality was a sharply focal rhythm at 7 ± 2 c/sec., in one or other parietal region; it was not much affected by eye-opening, startle, or overbreathing, and was usually readily distinguishable from the alpha rhythm, although the difference in frequency might be small ...

Midline Theta Rhythm Revisited
Clinical Electroencephalography, 1993The midline theta rhythm consists of runs of theta waves occurring in the midline, especially in the central and parietal vertex regions. Few reports regarding this uncommon EEG finding have been published. It has been given various names, e.g. theta discharges in the middle-line, theta spindles, etc. Out of the 4,236 patients who were administered EEG

GABAergic mediation of hippocampal theta rhythm induced by stimulation of the vagal nerve.
Brain Research Bulletin, 2019The key question to be answered in the present study was whether the medial septal GABAergic receptors are engaged in the pharmacological profile of the hippocampal formation (HPC) theta rhythm induced by vagal nerve stimulation (VNS).

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.
