Enhancing memory capacity by experimentally slowing theta frequency oscillations using combined EEG-tACS
(Nature Portfolio, 2022)
he coupling of gamma oscillation (similar to 40+ Hz) amplitude to the phase of ongoing theta (similar to 6 Hz) oscillations has been proposed to be directly relevant for memory performance. Current theories suggest that ...
The modulation of delta responses in the interaction of brightness and emotion
(Elsevier Science Bv, 2017)
The modulation of delta oscillations (0.5-3.5 Hz) by emotional stimuli is reported. Physical attributes such as color, brightness and spatial frequency of emotional visual stimuli have crucial effect on the perception of ...
A fast transform for brain connectivity difference evaluation
(Humana Press Inc, 2022)
Anatomical and dynamical connectivity are essential to healthy brain function. However, quantifying variations in connectivity across conditions or between patient populations and appraising their functional significance ...
Decrease of delta oscillatory responses in cognitively normal parkinson's disease
(Sage Publications Inc, 2017)
Parkinson's disease (PD) is a common progressive neurodegenerative disorder. This study aims to compare sensory-evoked oscillations (SEOs) and event-related oscillations (EROs) of visual modality in cognitively normal PD ...
Reactivity of posterior cortical electroencephalographic alpha rhythms during eyes opening in cognitively intact older adults and patients with dementia due to Alzheimer's and Lewy body diseases
(Elsevier Inc., 2022)
Please modify the Abstract as follows:Here we tested if the reactivity of posterior resting-state electroencephalographic (rsEEG) alpha rhythms from the eye-closed to the eyes-open condition may differ in patients with ...
Functional cortical source connectivity of resting state electroencephalographic alpha rhythms shows similar abnormalities in patients with mild cognitive impairment due to Alzheimer's and Parkinson's diseases
(Elsevier Ireland Ltd, 2018)
Objective: This study tested the hypothesis that markers of functional cortical source connectivity of resting state eyes-closed electroencephalographic (rsEEG) rhythms may be abnormal in subjects with mild cognitive ...
Abnormalities of cortical neural synchronization mechanisms in subjects with mild cognitive impairment due to Alzheimer's and Parkinson's diseases: An EEG study
(IOS Press, 2017)
The aim of this retrospective and exploratory study was that the cortical sources of resting state eyes-closed electroencephalographic (rsEEG) rhythms might reveal different abnormalities in cortical neural synchronization ...
The therapeutic role of repetitive transcranial magnetic stimulation (rTMS) in parkinsonian visual hallucinations: Electrophysiological correlates
(Elsevier Science Ltd, 2019)
We have evaluated an 82 years old PD patient who has acutely developed VH secondary to acute visual loss that was associated with increased electroencephalographic activity in the gamma range over the parietal, occipital ...
Time irreversibility of resting-state activity in the healthy brain and pathology
(Frontiers Media S.A., 2020)
Characterizing brain activity at rest is of paramount importance to our understanding both of general principles of brain functioning and of the way brain dynamics is affected in the presence of neurological or psychiatric ...
Resting state alpha electroencephalographic rhythms are differently related to aging in cognitively unimpaired seniors and patients with alzheimer's disease and amnesic mild cognitive impairment
(IOS Press, 2021)
Background: In relaxed adults, staying in quiet wakefulness at eyes closed is related to the so-called resting state electroencephalographic (rsEEG) rhythms, showing the highest amplitude in posterior areas at alpha ...
