Kognisyonun ritimleri: Bellek performansları üzerinde ölçülebilir etki ile nöral osilasyonları modüle etmek için transkraniyal alternatif akım uyarımının kullanılması
Aktürk, Tuba (İstanbul Medipol Üniversitesi, Sağlık Bilimleri Enstitüsü, 2022)Bu çalışma, beyin osilasyonları ile kognitif süreçler arasındaki fonksiyonel ilişkiyi test etmeyi, elektroensefalografi (EEG) verisi üzerinden bireyselleştirilmiş transkraniyal alternatif akım uyarımı (tAAU) uygulamasıyla ... -
Lower oddball event-related EEG delta and theta responses in patients with dementia due to Parkinson's and Lewy body than Alzheimer's disease
Yıldırım, Ebru; Aktürk, Tuba; Hanoğlu, Lütfü; Yener, Görsev; Babiloni, Claudio; Güntekin, Bahar (Elsevier Inc., 2024)Oddball task-related EEG delta and theta responses are associated with frontal executive functions, which are significantly impaired in patients with dementia due to Parkinson's disease (PDD) and Lewy bodies (DLB). The ... -
Oscillatory delta and theta frequencies differentially support multiple items encoding to optimize memory performance during the digit span task
Aktürk, Tuba; de Graaf, Tom A.; Erdal, Furkan; Sack, Alexander T.; Güntekin, Bahar (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 ... -
Reconstructing brain functional networks through identifiability and deep learning
Zanin, Massimiliano; Aktürk, Tuba; Yıldırım, Ebru; Yerlikaya, Deniz; Yener, Görsev; Güntekin, Bahar (MIT Press Journals, 2024)We propose a novel approach for the reconstruction of functional networks representing brain dynamics based on the idea that the coparticipation of two brain regions in a common cognitive task should result in a drop in ... -
Resting state alpha electroencephalographic rhythms are differently related to aging in cognitively unimpaired seniors and patients with alzheimer's disease and amnesic mild cognitive impairment
Babiloni, Claudio; Ferri, Raffaele; Noce, Giuseppe; Lizio, Roberta; Lopez, Susanna; Lorenzo, Ivan; Tucci, Federico; Soricelli, Andrea; Nobili, Flavio; Arnaldi, Dario; Fama, Francesco; Orzi, Francesco; Buttinelli, Carla; Giubilei, Franco; Cipollini, Virginia; Marizzoni, Moira; Güntekin, Bahar; Aktürk, Tuba; Hanoğlu, Lütfü; Yener, Görsev; Özbek, Yağmur; Stocchi, Fabrizio; Vacca, Laura; Frisoni, Giovanni B.; del Percio, Claudio (IOS Press, 2021)Background: In relaxed adults, staying in quiet wakefulness at eyes closed is related to the so-called resting state electroencephalographic (rsEEG) rhythms, showing the highest amplitude in posterior areas at alpha ... -
Resting-state electroencephalographic delta rhythms may reflect global cortical arousal in healthy old seniors and patients with Alzheimer's disease dementia
Babiloni, Claudio; Ferri, Raffaele; Noce, Giuseppe; Lizio, Roberta; Lopez, Susanna; Soricelli, Andrea; Nobili, Flavio; Arnaldi, Dario; Fama, Francesco; Orzi, Francesco; Buttinelli, Carla; Giubilei, Franco; Cipollini, Virginia; Marizzoni, Moira; Güntekin, Bahar; Aktürk, Tuba; Hanoğlu, Lütfü; Yener, Görsev; Emek Savaş, Derya Durusu; Stocchi, Fabrizio; Vacca, Laura; Frisoni, Giovanni B.; Del Percio, Claudio (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 ... -
rTMS reduces delta and increases theta oscillations in Alzheimer's disease: A visual-evoked and event-related potentials study
Velioğlu, Halil Aziz; Düdükçü, Esra Zeynep; Hanoğlu, Lütfü; Güntekin, Bahar; Aktürk, Tuba; Yuluğ, Burak (Wiley, 2024)Background: Repetitive transcranial magnetic stimulation (rTMS) has emerged as a promising alternative therapy for Alzheimer's disease (AD) due to its ability to modulate neural networks and enhance cognitive function. ... -
Telling functional networks apart using ranked network features stability
Zanin, Massimiliano; Güntekin, Bahar; Aktürk, Tuba; Yıldırım, Ebru; Yener, Görsev; Kıyı, İlayda; Hünerli Gündüz, Duygu; Sequeira, Henrique; Papo, David (NLM (Medline), 2022)Over the past few years, it has become standard to describe brain anatomical and functional organisation in terms of complex networks, wherein single brain regions or modules and their connections are respectively identified ... -
The therapeutic role of repetitive transcranial magnetic stimulation (rTMS) in parkinsonian visual hallucinations: Electrophysiological correlates
Hanoğlu, Taha; Hanoğlu, Lütfü; Güntekin, Bahar; Aktürk, Tuba; Yuluğ, Burak (Elsevier Science Ltd, 2019)We have evaluated an 82 years old PD patient who has acutely developed VH secondary to acute visual loss that was associated with increased electroencephalographic activity in the gamma range over the parietal, occipital ... -
Theta and alpha oscillatory responses differentiate between six-to seven-year-old children and adults during successful visual and auditory memory encoding
Güntekin, Bahar; Uzunlar, Hakan; Çalışoğlu, Pervin; Eroğlu-Ada, Figen; Yıldırım, Ebru; Aktürk, Tuba; Atay, Enver; Ceran, Ömer (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 ... -
Time irreversibility of resting-state activity in the healthy brain and pathology
Zanin, Massimiliano; Güntekin, Bahar; Aktürk, Tuba; Hanoǧlu, Lütfü; Papo, David (Frontiers Media S.A., 2020)Characterizing brain activity at rest is of paramount importance to our understanding both of general principles of brain functioning and of the way brain dynamics is affected in the presence of neurological or psychiatric ... -
