Role of the Medial Septal Area in Regulating Prefrontal Theta Rhythm in Rats [PDF]
, 2007 Theta rhythms are electroencephalogram (EEG) waveforms between 4-12 Hz and are correlated with arousal, orientation, exploration, attention, learning and memory, motivational drives and emotions and movements.

International Studies of Economics, EarlyView.ABSTRACT Financial markets can be viewed as multiscale information systems in which short‐lived disturbances, recurrent temporal patterns, liquidity conditions, and execution constraints jointly shape index price movements. This study develops an empirical‐wavelet‐and‐Fourier time‐frequency (EFT) feature block integrated with a ConvTransformer ...

Unmasking the Theta Method. [PDF]
The Theta method of forecasting performed particularly well in the M3-competition and is therefore of interest to forecast practitioners. The description of the method given by Assimakopoulos and Nikolopoulos (2000) involves several pages of algebraic ...

Journal of Intelligent Medicine, EarlyView.Abstract Simultaneous electroencephalography (EEG) recording during transcranial alternating current stimulation (tACS) is strongly contaminated by stimulation artifacts, limiting direct assessment of neural activity. Steady‐state visual evoked potentials (SSVEPs) provide frequency‐specific and phase‐locked responses, making them suitable for ...

The Kaohsiung Journal of Medical Sciences, EarlyView.ABSTRACT Minimal hepatic encephalopathy (MHE) involves subtle cognitive dysfunction and systemic inflammation and is associated with an increased risk of overt hepatic encephalopathy. The Animal Naming Test (ANT1) is a rapid semantic fluency tool for MHE assessment, but its performance across different primary spoken languages remains unclear.

Closed-loop control of theta oscillations enhances human hippocampal network connectivity
Nature CommunicationsTheta oscillations are implicated in regulating information flow within cortico-hippocampal networks to support memory and cognition. However, causal evidence tying theta oscillations to network communication in humans is lacking.

Afferent influences on the hippocampal theta rhythm
, 1976 Includes bibliographical references (pages 71-80)The hippocampus has been implicated in mechanisms of learning and memory. Theta, a synchronous ESG rhythm, is the prominent electrophysiological characteristic of that structure.
