Delta and theta oscillatory activity in human information processing

Karakaş, Sirel (Dogus Author) -- Conference full title: Proceedings of the 18th World Congress of Psychophysiology (IOP2016) of the International Organization of Psychophysiology (IOP) Havana, Cuba August 31st to September 4th, 2016.Previous studies showed that event related EEG delta coherence increased upon application of cognitive load in healthy young subjects. The decrease of delta coherence in Alzheimer’s disease patients was reported in comparison to healthy controls during cognitive load. However, when the stimulation was just visual sensory no differences between healthy controls and Alzheimer patients were found (Başar et al. 2010, Güntekin et al. 2008). The present study aims to analyze event related delta coherence in patients with Parkinson’s disease with and without cognitive deficits during application of visual oddball paradigm
