Reduced power and phase-locking values were accompanied by thalamus, putamen, and hippocampus atrophy in Parkinson's disease with mild cognitive impairment: An event-related oscillation study
(Elsevier Inc., 2023)
Parkinson's disease (PD) is a multifaceted neurodegenerative disorder accompanied by mild cognitive impairment (MCI) as a crucial nonmotor manifestation. Event-related oscillations (EROs) are suggested to reflect cognitive ...
Oscillatory delta and theta frequencies differentially support multiple items encoding to optimize memory performance during the digit span task
(Academic Press Inc., 2022)
The human brain has limited storage capacity often challenging the encoding and recall of a long series of multiple items. Different encoding strategies are therefore employed to optimize performance in memory processes ...
Distinct brain oscillatory responses for the perception and identification of one's own body from other's body
(Springer, 2021)
The body recognition process includes complex visual processing, the sensation, perception, and distinction stages of the stimulus. This study examined this process by using the time-frequency analysis of EEG signals and ...
Cognitive impairment in parkinson's disease is reflected with gradual decrease of eeg delta responses during auditory discrimination
(Frontiers Media Sa, 2018)
Parkinson's disease (PD) is a neurodegenerative disease that is characterized by loss of dopaminergic neurons in the substantia nigra. Mild Cognitive impairment (MCI) and dementia may come along with the disease. New ...
Treatment effects on event-related EEG potentials and oscillations in Alzheimer's disease
(Elsevier B.V., 2022)
Alzheimer's disease dementia (ADD) is the most diffuse neurodegenerative disorder belonging to mild cognitive impairment (MCI) and dementia in old persons. This disease is provoked by an abnormal accumulation of amyloid-beta ...
Event-related brain oscillatory responses topographically differentiated between visual and auditory emotional stimuli
(Elsevier, 2023)
Previous EEG studies using emotional stimuli have successfully demonstrated that EEG-brain oscillation responses are sensitive to the valance and arousal of the stimulus. While the valance is represented by increased beta ...
Resting state electroencephalographic alpha rhythms predict and are sensitive to Alzheimer's disease mild cognitive impairment progression at a 6-month follow-up
(Elsevier, 2023)
Introduction: Patients with Alzheimer’s disease and mild cognitive impairment (ADMCI) suffer not only from severe cognitive deficits and disabilities in daily living but also from vigilance dysregulation reflected by ...
Alterations of resting-state Gamma frequency characteristics in aging and Alzheimer's disease
(Springer, 2023)
Alzheimer's disease (AD) is an important brain disease associated with aging. It involves various functional and structural changes which alter the EEG characteristics. Although numerous studies have found changes in delta, ...
Abnormal cross frequency coupling of brain electroencephalographic oscillations related to visual oddball task in parkinson's disease with mild cognitive impairment
(SAGE Publications Inc., 2023)
Parkinson's disease (PD) is a movement disorder caused by degeneration in dopaminergic neurons. During the disease course, most of PD patients develop mild cognitive impairment (PDMCI) and dementia, especially affecting ...
Event-related delta and theta responses may reflect the valence discrimination in the emotional oddball task
(Springer Science and Business Media Deutschland GmbH, 2023)
How emotion and cognition interact is still a matter of debate. Investigation of this interaction in terms of the brain oscillatory dynamics appears to be an essential approach. To investigate this topic, we designed two ...
