Journal ArticleDOI
A comparative analysis of speech signal processing algorithms for Parkinson’s disease classification and the use of the tunable Q-factor wavelet transform
C. Okan Sakar,Gorkem Serbes,Aysegul Gunduz,Hunkar Can Tunc,Hatice Nizam,Betul Erdogdu Sakar,Melih Tutuncu,Tarkan Aydin,M. Erdem Isenkul,Hulya Apaydin +9 more
TL;DR: The results show that TQWT performs better or comparable to the state-of-the-art speech signal processing techniques used in PD classification, and Mel-frequency cepstral and the tunable-Q wavelet coefficients, which give the highest accuracies, contain complementary information inPD classification problem resulting in an improved system when combined using a filter feature selection technique.
Journal ArticleDOI
The interleukin 1 alpha, interleukin 1 beta, interleukin 6 and alpha-2-macroglobulin serum levels in patients with early or late onset Alzheimer's disease, mild cognitive impairment or Parkinson's disease
Erdinç Dursun,Duygu Gezen-Ak,Hasmet Hanagasi,Başar Bilgiç,Ebba Lohmann,Sibel Ertan,Irem L. Atasoy,Merve Alaylıoğlu,Ömür Selin Araz,Burak Önal,Aysegul Gunduz,Hulya Apaydin,Güneş Kızıltan,Turgut Ulutin,Hakan Gurvit,Selma Yilmazer +15 more
TL;DR: The MCI data indicate that IL-1s, α2M and BDNF are somehow related, and this relationship might allow MCI patients to be more similar to the healthy controls.
Journal ArticleDOI

TL;DR: Deep brain stimulation was associated with symptomatic improvement in patients with Tourette syndrome but also with important adverse events, including intracranial hemorrhage and infection.
Journal ArticleDOI
The tracking of speech envelope in the human cortex.
Jan Kubanek,Peter Brunner,Peter Brunner,Aysegul Gunduz,Aysegul Gunduz,David Poeppel,Gerwin Schalk,Gerwin Schalk +7 more
TL;DR: The data provide the first direct electrophysiological evidence that the envelope of speech is robustly tracked in non-primary auditory cortex (belt areas in particular), and suggest that the considered higher-order regions (STG and Broca's region) partake in a more abstract linguistic analysis.
Journal ArticleDOI
Recording Human Electrocorticographic (ECoG) Signals for Neuroscientific Research and Real-time Functional Cortical Mapping
N. Jeremy Hill,Disha Gupta,Disha Gupta,Peter Brunner,Peter Brunner,Aysegul Gunduz,Aysegul Gunduz,Matthew A. Adamo,Anthony L. Ritaccio,Gerwin Schalk +9 more
TL;DR: The methods for collecting recording ECoG are described, and how to use these signals for important real-time applications such as clinical mapping and brain-computer interfacing are demonstrated.
