Uncertainty, anxiety, and brain oscillations
Neuroscience Letters, 2005Influence of anxious expectation on spectral power and delta-gamma coupling was studied in 39 subjects (27 females) aged 19-30 years who also filled out the State Trait Anxiety Inventory. The situation of uncertainty was associated with general increase in spectral power of all EEG bands, which was particularly pronounced in high-trait anxiety subjects.

Dimensionality reduction for the analysis of brain oscillations
NeuroImage, 2014 Neuronal oscillations have been shown to be associated with perceptual, motor and cognitive brain operations. While complex spatio-temporal dynamics are a hallmark of neuronal oscillations, they also represent a formidable challenge for the proper extraction and quantification of oscillatory activity with non-invasive recording techniques such as EEG ...

Brain oscillations evoked by sound motion
Brain Research, 2021The present study investigates the event-related oscillations underlying the motion-onset response (MOR) evoked by sounds moving at different velocities. EEG was recorded for stationary sounds and for three patterns of sound motion produced by changes in interaural time differences.

Personality, gender and brain oscillations
International Journal of Psychophysiology, 2007The aim of the study was to investigate the relationship between personality structure and brain activity of individuals while resting with eyes closed. In the experiment 110 individuals participated (55 males and 55 females). They were clustered into 5 personality types according to the dimensions of general and emotional intelligence, and the five ...

Oscillating circuitries in the sleeping brain
Nature Reviews Neuroscience, 2019Brain activity during sleep is characterized by circuit-specific oscillations, including slow waves, spindles and theta waves, which are nested in thalamocortical or hippocampal networks. A major challenge is to determine the relationships between these oscillatory activities and the identified networks of sleep-promoting and wake-promoting neurons ...

Brain Oscillations and the Importance of Waveform Shape
Trends in Cognitive Sciences, 2017Oscillations are a prevalent feature of brain recordings. They are believed to play key roles in neural communication and computation. Current analysis methods for studying neural oscillations often implicitly assume that the oscillations are sinusoidal.

Neuropharmacology of altered brain oscillations in schizophrenia
International Journal of Psychophysiology, 2016Impairments in spatial and temporal integration of brain network activity are a core feature of schizophrenia. Neural network oscillatory activity is considered to be fundamentally important in coordinating neural activity throughout the brain. Hence, exploration of brain oscillations has become an indispensible tool to study the neural basis of mental

High-frequency oscillations in human brain
Hippocampus, 1999Ripples are 100-200 Hz short-duration oscillatory field potentials that have recently been recorded in rat hippocampus and entorhinal cortex. They reflect fast IPSPs on the soma of pyramidal cells, which occur during synchronous afferent excitation of principal cells and interneuron networks.

Thalamocortical Oscillations in the Sleeping and Aroused Brain
Science, 1993Sleep is characterized by synchronized events in billions of synaptically coupled neurons in thalamocortical systems. The activation of a series of neuromodulatory transmitter systems during awakening blocks low-frequency oscillations, induces fast rhythms, and allows the brain to recover full responsiveness.

Low-Frequency Brain Oscillations in Schizophrenia
JAMA Psychiatry, 2016Understanding thebrainnetworks thatproduce thesymptomsof schizophrenia is a major goal of modern neuroscience. There is increasing evidence that brain function depends critically on oscillations, and ithas thereforebeenof interest todeterminewhether the oscillatorypropertiesof thebrain areabnormal in schizophrenicpatients.
