Prominence of delta oscillatory rhythms in the motor cortex and their relevance for auditory and speech perception [PDF]

Neuroscience & Biobehavioral Reviews, 2019
In the motor cortex, beta oscillations (∼12-30 Hz) are generally considered a principal rhythm contributing to movement planning and execution. Beta oscillations cohabit and dynamically interact with slow delta oscillations (0.5-4 Hz), but the role of delta oscillations and the subordinate relationship between these rhythms in the perception-action ...

Electroencephalographic accompaniment of quantitative-qualitative blood pressure clusters in patients of Truskavets’ spa

Journal of Education, Health and Sport, 2021
Background. Earlier we studied the autonomic and endocrine accompaniments of quantitative-qualitative blood pressure (BP) clusters of profile patients of Truskavets’ spa.

Examining cortical tracking of the speech envelope in post-stroke aphasia

Frontiers in Human Neuroscience, 2023
IntroductionPeople with aphasia have been shown to benefit from rhythmic elements for language production during aphasia rehabilitation. However, it is unknown whether rhythmic processing is associated with such benefits.

IMF-Based MF and HS Energy Feature Information of F5, and F6 Movement and Motor Imagery EEG Signals in Delta Rhythms Using HHT

Sensors, 2023
This study aims to extract the energy feature distributions in the form of marginal frequency (MF) and Hilbert spectrum (HS) in the intrinsic mode functions (IMF) domain for actual movement (AM)-based and motor imagery (MI)-based electroencephalogram ...

Normal bilirubinemia downregulates the power spectral density of the θ and Δ rhythm, instead upregulates the β rhythm and sympatho-vagal balance in adults humans

Journal of Education, Health and Sport, 2022
Background. Neonatal hyperbilirubinemia has been known to damage neural function. Our goal is to determine whether the neurotropic activity of normal bilirubinemia in adults is evident. Methods. The object of observation were 77 volunteers: 30 women and

Analysis of electroencephalography brain rhythms in the reading process

Einstein (São Paulo), 2020
Objective: To verify if, by three distinct quantifiers, the measured electroencephalographic signal at rest is different from the signal measured during a word reading situation, especially considering the faster rhythms, gamma and high-gamma, as it ...

Independent delta/theta rhythms in the human hippocampus and entorhinal cortex [PDF]

Frontiers in Human Neuroscience, 2008
Theta oscillations in the medial temporal lobe (MTL) of mammals are involved in various functions such as spatial navigation, sensorimotor integration, and cognitive processing. While the theta rhythm was originally assumed to originate in the medial septum, more recent studies suggest autonomous theta generation in the MTL.

High-voltage, diffuse delta rhythms coincide with wakeful consciousness and complexity in Angelman syndrome [PDF]

Neuroscience of Consciousness, 2020
Abstract Abundant evidence from slow wave sleep, anesthesia, coma, and epileptic seizures links high-voltage, slow electroencephalogram (EEG) activity to loss of consciousness. This well-established correlation is challenged by the observation that children with Angelman syndrome (AS), while fully awake and displaying volitional ...

A prefrontal cortex alpha/delta switch controls the transition from positive to negative affective states

Discover Mental Health, 2023
Positive and negative emotional states in rats can be studied by investigating ultrasonic vocalizations (USVs). Positive affect in rats is indexed by 50 kHz hedonic USVs, and negative affect is indexed by 22 kHz aversive calls.
