EMPIRICAL MODE DECOMPOSITION BASED ON THETA METHOD FOR FORECASTING DAILY STOCK PRICE

Journal of ICT, 2020
Forecasting is a challenging task as time series data exhibit many features that cannot be captured by a single model. Therefore, many researchers have proposed various hybrid models in order to accommodate these features to improve forecasting results ...

Frontal Theta Oscillations in Perceptual Decision-Making Reflect Cognitive Control and Confidence [PDF]

Brain Sciences
Background: Perceptual decision-making requires transforming sensory inputs into goal-directed actions under uncertainty. Neural oscillations in the theta band (3–7 Hz), particularly within frontal regions, have been implicated in cognitive control and ...

Theta Oscillations Assessed From a Passive Auditory Oddball Paradigm in Individuals at Clinical High-Risk for Psychosis and Healthy Control Individuals: Associations with Clinical Outcomes and Mismatch Negativity [PDF]

Biological Psychiatry Global Open Science
Background: Reduced mismatch negativity (MMN) is a widely replicated schizophrenia biomarker. Time-frequency analyses suggest that deficient phase synchrony and/or power of electroencephalography (EEG) event-related oscillations, especially theta ...

Resting-state theta activity is linked to information content-specific coding levels during response inhibition

Scientific Reports, 2022
The neurophysiological processes underlying the inhibition of impulsive responses have been studied extensively. While also the role of theta oscillations during response inhibition is well examined, the relevance of resting-state theta activity for ...

Phase synchronized 6 Hz transcranial electric and magnetic stimulation boosts frontal theta activity and enhances working memory

NeuroImage, 2021
Network-level synchronization of theta oscillations in the cerebral cortex is linked to many vital cognitive functions across daily life, such as executive functions or regulation of arousal and consciousness.

Prefrontal theta phase-dependent rTMS-induced plasticity of cortical and behavioral responses in human cortex

Brain Stimulation, 2022
Background: Prefrontal theta oscillations are involved in neuronal information transfer and retention. Phases along the theta cycle represent varied excitability states, whereby high-excitability states correspond to high-frequency neuronal activity and ...
