Delta oscillatory responses as a general electrophysiological biomarker for cognitive disorders
(Elsevier Science Bv, 2016)
Background: In the last decade research on delta oscillatoryresponses invaded the literature. One of thefirst research on thisarea showed that delta responses increase upon cognitive load(Başar and Stampfer 1985). After ...
Abnormal event related EEG delta coherence in Parkinson type of dementia during the visual oddball paradigm
(Elsevier Science Ltd., 2016)
…
Theta and alpha oscillatory responses differentiate between six-to seven-year-old children and adults during successful visual and auditory memory encoding
(Elsevier, 2020)
The healthy maturation of the brain is one of the intriguing topics that need to be investigated to understand human brain and child development. The present study aimed to investigate the development of memory processes ...
Abnormalities in auditory and visual cognitive processes are differentiated with theta responses in patients with Parkinson's disease with and without dementia
(Elsevier, 2020)
The research on the abnormalities of event-related oscillations in Parkinson's disease (PD) was mostly studied with cognitively normal patients. The present study aims to show the adverse effects of cognitive decline in ...
Resting-state electroencephalographic delta rhythms may reflect global cortical arousal in healthy old seniors and patients with Alzheimer's disease dementia
(Elsevier, 2020)
Extending Basar's theory of event-related EEG oscillations, here we hypothesize that even in quiet wakefulness, transient increases in delta rhythms may enhance global cortical arousal as revealed by the desynchronization ...
Impairment in recognition of emotional facial expressions in Alzheimer's disease is represented by EEG theta and alpha responses
(Blackwell Publishing Inc., 2019)
Behavioral studies have shown that the recognition of facial expressions may be impaired in patients with Alzheimer's disease (AD). The identification and recognition of a facial expression might be represented by event-related ...
The difference of mild cognitive impairment in Parkinson's disease from amnestic mild cognitive impairment: Deeper power decrement and no phase-locking in visual event-related responses
(Elsevier Science Bv, 2019)
Event-related oscillatory responses reflect the cognitive status in many neuropsychiatric conditions including mild cognitive impairment (MCI). In this study, a total of 30 patients with amnestic MCI (aMCI) and 25 patients ...
EEG measures for clinical research in major vascular cognitive impairment: recommendations by an expert panel
(Elsevier Inc., 2021)
Vascular contribution to cognitive impairment (VCI) and dementia is related to etiologies that may affect the neurophysiological mechanisms regulating brain arousal and generating electroencephalographic (EEG) activity. A ...
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 ...
Electrophysiological evidence of altered facial expressions recognition in Alzheimer's disease: A comprehensive ERP study
(Elsevier Ireland Ltd, 2019)
Objectives: The present study aims to evaluate the amplitude and latency of event-related potentials (ERPs) P100, N170, VPP and N230 in individuals with Alzheimer's disease (AD) compared to healthy elderly controls, using ...
