A New Interpretation Of P300 Responses Upon Analysis Of Coherences
(Springer, Van Godewijckstraat 30, 3311 Gz Dordrecht, Netherlands, 2010-06)
Previous studies on cognitive dynamics showed that oscillatory responses of P300 are composed of mainly delta and theta responses. In the present study, for the first time, the long-distance intra-hemispheric event related ...
Disturbance In Long Distance Gamma Coherence In Bipolar Disorder
(Pergamon-Elsevier Science Ltd, The Boulevard, Langford Lane, Kidlington, Oxford Ox5 1Gb, England, 2010-08-16)
The aim of this study was to investigate long distance event-related gamma (28-48 Hz) coherence in mania before and after valproate monotherapy. Gamma coherence in response to visual oddball paradigm in ten medication-free, ...
Evoked And Event Related Coherence Of Alzheimer Patients Manifest Differentiation Of Sensory-Cognitive Networks
(Elsevier Science Bv, Po Box 211, 1000 Ae Amsterdam, Netherlands, 2010-10-21)
In previous studies on Alzheimer's patients it was shown that, in frontal and parietal locations, delta and theta responses of AD patients were greatly reduced. The present study analyzed coherence functions in these highly ...
Brain's alpha activity is highly reduced in euthymic bipolar disorder patients
(Springer, Van Godewijckstraat 30, 3311 Gz Dordrecht, Netherlands, 2012-02)
Brain's alpha activity and alpha responses belong to major electrical signals that are related to sensory/cognitive signal processing. The present study aims to analyze the spontaneous alpha activity and visual evoked alpha ...
Event-Related Beta Oscillations Are Affected By Emotional Eliciting Stimuli
(Elsevier Ireland Ltd, Elsevier House, Brookvale Plaza, East Park Shannon, Co, Clare, 00000, Ireland, 2010-10-15)
According to previous results, negative emotional facial expressions elicit oscillatory beta responses The present study analyzes event-related beta oscillations upon presentation of International Affective Picture System ...
A short review of alpha activity In cognitive processes and in cognitive impairment
(Elsevier Science Bv, Po Box 211, 1000 Ae Amsterdam, Netherlands, 2012-10)
Aim of the report: In the companion report (Basar, this volume), the physiological fundaments of alpha activity in integrative brain function are described. The present report is a review of the significant role of alpha ...
Is research on brain oscillations in a new "Take Off-State" in integrative brain function?
(Elsevier Science Bv, Po Box 211, 1000 Ae Amsterdam, Netherlands, 2012-09)
Theta Oscillations Are Diminished In Medication-Free Euthymic Patients With Bipolar Disorder
(Wiley-Blackwell, Commerce Place, 350 Main St, Malden 02148, Ma Usa, 2011-06)
The Effects Of Rasagiline On Cognitive Deficits in Parkinson's Disease Patients Without Dementia: A Randomized, Double-Blind, Placebo-Controlled, Multicenter Study
(Wiley-Blackwell, Commerce Place, 350 Main St, Malden 02148, Ma Usa, 2011-08-15)
Cognitive impairment can occur at all stages of Parkinson's disease. Rasagiline is a selective monoamine oxidase type-B inhibitor that enhances central dopaminergic transmission. Dopamine is thought to be involved in certain ...
Sensory Evoked And Event Related Oscillations In Alzheimer's Disease: A Short Review
(Springer, Van Godewijckstraat 30, 3311 Gz Dordrecht, Netherlands, 2010)
Diagnosis and treatment of Alzheimer's disease (AD) depend on clinical evaluation and there is a strong need for an objective tool as a biomarker. Our group has investigated brain oscillatory responses in a small group of ...
