2n-dimensional at Fujii model instanton-like solutions and coupling constant’s role between instantons with higher derivatives
(2011)An instanton-like solution is considered for a class of two-dimensional conformal model with Liouville term. The model expressed here is a new higher-dimensional model with scalar-spinor interaction on evendimensional ... -
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 ... -
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 ... -
Abnormalities of cortical neural synchronization mechanisms in patients with dementia due to Alzheimer's and Lewy body diseases: An EEG study
(Elsevier Science Inc., 2017)The aim of this retrospective exploratory study was that resting state eyes-closed electroencephalographic (rsEEG) rhythms might reflect brain arousal in patients with dementia due to Alzheimer's disease dementia (ADD), ... -
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 ... -
Abnormalities of cortical sources of resting state alpha electroencephalographic rhythms are related to education attainment in cognitively unimpaired seniors and patients with alzheimer's disease and amnesic mild cognitive impairment
(NLM (Medline), 2021)In normal old (Nold) and Alzheimer's disease (AD) persons, a high cognitive reserve (CR) makes them more resistant and resilient to brain neuropathology and neurodegeneration. Here, we tested whether these effects may ... -
Abnormalities of resting state cortical EEG rhythms in subjects with mild cognitive impairment due to alzheimer's and lewy body diseases
(IOS Press, 2018)The present study tested the hypothesis that cortical sources of resting state eyes-closed electroencephalographic (rsEEG) rhythms reveal different abnormalities in cortical neural synchronization in groups of patients ... -
Abnormalities of resting-state functional cortical connectivity in patients with dementia due to alzheimer's and lewy body diseases: An EEG study
(Elsevier Science Inc, 2018)Previous evidence showed abnormal posterior sources of resting-state delta (<4 Hz) and alpha (8-12 Hz) rhythms in patients with Alzheimer's disease with dementia (ADD), Parkinson's disease with dementia (PDD), and Lewy ... -
Age related differences in the recognition of facial expression: Evidence from EEG event-related brain oscillations
(Elsevier B.V., 2020)Facial Expression (FE) recognition is a major marker of emotional ability. Behavioral studies show that FE recognition ability decreases with aging. Studying how event-related brain oscillations change with normal aging ... -
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, ... -
Are there consistent abnormalities in event-related EEG oscillations in patients with Alzheimer's disease compared to other diseases belonging to dementia?
(John Wiley and Sons Inc, 2022)Cerebrospinal and structural-molecular neuroimaging in-vivo biomarkers are recommended for diagnostic purposes in Alzheimer’s disease (AD) and other dementias; however, they do not explain the effects of AD neuropathology ... -
Brain health in diverse settings: How age, demographics and cognition shape brain function
(2024)Diversity in brain health is influenced by individual differences in demographics and cognition. However, most studies on brain health and diseases have typically controlled for these factors rather than explored their ... -
Classification of Parkinson's disease with dementia using phase locking factor of event-related oscillations to visual and auditory stimuli
(IOP Publishing Ltd, 2023)Objective. In the last decades, machine learning approaches have been widely used to distinguish Parkinson’s disease (PD) and many other neuropsychiatric diseases. They also speed up the clinicians and facilitate decision-making ... -
Classification of patients with alzheimer's disease and dementia with lewy bodies using resting EEG selected features at sensor and source levels: A proof-of-concept study
(Bentham Science, 2021)Background: Early differentiation between Alzheimer's disease (AD) and Dementia with Lewy Bodies (DLB) is important for accurate prognosis, as DLB patients typically show faster disease progression. Cortical neural networks, ... -
Corrigendum to ‘‘Functional cortical source connectivity of resting stateelectroencephalographic alpha rhythms shows similar abnormalitiesin patients with mild cognitive impairment due to Alzheimer’s and Parkinson’s diseases” [Clin. Neurophysiol. 129 (2018) 766–782]
(Elsevier Ireland Ltd., 2019)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 ... -
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 ... -
Distinct brain oscillatory responses for the perception and identification of one's own body from other's body
