Minimum Spanning Tree Reflects the Alterations of the Default Mode Network During Alzheimer's Disease
Çiftçi, Koray (Springer, 2011)This study analyzes the connectivity pattern of the default mode network (DMN) in patients with Alzheimer's disease (AD) in comparison with young and elderly controls using the minimum spanning tree (MST). This tree is a ... -
On Temporal Connectivity of PFC Via Gauss-Markov Modeling of fNIRS Signals
Aydore, Sergul; Mihcak, M. Kivanc; Çiftçi, Koray; Akın, Ata (IEEE-Inst Electrical Electronics Engineers Inc, 2010)Functional near-infrared spectroscopy (fNIRS) is an optical imaging method, which monitors the brain activation by measuring the successive changes in the concentration of oxy- and deoxyhemoglobin in real time. In this ... -
Synaptic noise facilitates the emergence of self-organized criticality in the Caenorhabditis elegans neuronal network
Çiftçi, Koray (Taylor and Francis Ltd, 2018)Avalanches with power-law distributed size parameters have been observed in neuronal networks. This observation might be a manifestation of self-organized criticality (SOC). Yet, the physiological mechanisms of this behaviour ...
