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 ... -
Synchronization Cost of Coupled Oscillators with a Spatial Embedding
Çiftçi, Koray (Institute of Electrical and Electronics Engineers Inc., 2019)Synchronous behavior brings advantages for complex systems. Yet, this advantage comes with a cost: Emergence and sustainability of synchronization requires a continuous exchange among the interacting units. Thus, networks ...
